Summarize this article in one sentence.
If you're lucky enough to have a special someone, then you should make your time together meaningful. Don't stop doing the things you love with the person you love, making time to say "I love you", or just spending time with your special someone. Being around your loved one and having positive interactions with him or her has been proven to make people happier, so don't shrug off this obvious mood-lifter if you have the chance to use it.  If you do have a partner, then having regular sex, at least a few times a week, has proven to help people stay in a good mood, too! You may think that, just because your worries are work or school related, that your loved one won't be able to make you feel better about it. That's where you're wrong! This will release endorphins that will improve your mood. Regular exercise is one of the most important habits that you want to cultivate. On average, you should get at least 30 minutes of exercise a day, but you don't have to do the same boring old thing every day. You can go running three times a week and walk the other four; you can do yoga four times a week and give yourself an off day or two. Just make sure to be as active as you can every day, whether this means taking the stairs instead of the elevator or walking instead of driving. Hanging out with friends will keep you feeling energized, excited about being alive, and like you're really spending time with the people who care about you. Of course, if you're always hanging out with friends when you have a free moment, you may actually feel a bit overwhelmed and like you have no time to decompress. Make sure you do make time to see friends at least once or twice a week, if you can. The next time your friends beg you to come out when you're feeling too lazy or sorry for yourself, come out! You'll feel better right away.  Of course, if you're not feeling it, you don't have to hang out with your friends. But if you make spending time with friends a bigger priority, then this habit will lead to a better mood, long term. And hey, if you spend time with friends who tend to be happy and love laughter, then they'll make you feel happier, too. If you're hanging out with a bunch of Debbie Downers, then you won't be on your way to a better mood. Make sure to sleep for at least 7-8 hours a day and to go to bed and wake up around the same time every night to get into a healthy routine. One of the easiest ways to stay in a good mood is to be well-rested. Waking up feeling full of energy will make you feel much more ready to face the day and much more excited about everything ahead of you -- and more capable of dealing with it. Make sure that sleep is a priority over watching late-night TV or doing other tasks you can save until the morning. Read a good book or watch a feel-good movie and then journal before you go to bed. Have a positive conversation with your loved one before you drift off. Whatever you do, don't do anything too stressful, like writing a paper or upsetting, like watching crimes on the nightly news, before you drift off, or you'll be more likely to have bad dreams and restless sleep and to wake up cranky.  When you get up, read a good book or the sports section of the paper. Also, give yourself a few minutes of peace before you turn on your phone or computer; this will help you feel like you're present in the moment before you really start your day. Try decreasing the amount of negative news you consume overall. Don't tune out major events, but don't constantly consume negative news, either. Negative information tends to be more memorable, and it can impact how you feel throughout your day.  Try decreasing the amount of social media you use, too. Too much time on social media can make you compare your life to others. Since social media often shows the best parts of other people's lives, consuming too much can make you feel unnecessarily bad about your own life. If you want to stay in a good mood, then you have to make sure to eat three healthy and diverse meals every day. Start off with a healthy breakfast, which can have lean proteins like turkey and healthy veggies like spinach, and don't skip this meal no matter what. Have light snacks throughout the day, like yogurt or fruit, to keep you energized, and avoid overeating or going more than three hours without eating at least a little something. Your energy levels affect your mood, and it's important to have regular and healthy meals to feel up to speed. You may start to feel less happy because you're getting lethargic as a result of not drinking enough. Drinking a glass of water will instantly wake up your mind and body. Make sure to drink whenever you feel thirsty. Your body will let you know whenever you're feeling a little dehydrated. Whether you're working on your novel or love sculpting, make sure to give yourself enough time to pursue your passion throughout the week, even if it feels like you have a million other things going on. At the end of the day, doing what you really love will make you feel better than doing what you really need to do, and if you want to be a happy person who is able to stay in a good mood, then you've got to make time for what you really love. Giving your time on a regular basis will definitely make you stay in a good mood more often. You'll feel good about helping people, whether you're helping adults learn to read, cleaning up a local park, or volunteering at a soup kitchen. Helping people and making other people happier on the regular will actually make you happier, too. Take just 10 minutes out of your day to find a comfortable seat in a quiet room, focus on your breath, and feel each of your body parts relaxing, one at a time. Focus only on your breath rising in and out of your body and let the rest of your thoughts melt away. Making a habit of meditating every morning, evening, or whatever you feel like it has been proven to help people stay in a good mood.  There are a number of smartphone apps available to help guide and time your meditations. These can be especially helpful if you're new to meditating. If meditation isn't your thing, you can also try yoga, which can also help you focus, unwind, and live a happier life. Though you may not be in a good mood just because you didn't get enough sleep or for another reason that can be addressed pretty easily, you may not be able to stay in a good mood because you don't feel a sense of accomplishment or fulfillment. Setting a goal, even a small goal, can help increase your self-esteem. If you think there are major reasons you struggle to stay happy, such as a dead-end job or a difficult relationship, try setting a goal to make a major change. Then, break your larger goal into smaller actions and focus on one action at a time. Every time you complete one, you will feel a little better and be a little closer to your goal. A lot of people lose their good moods because they get upset about things like losing their umbrellas, having a bad interaction with a mean coworker, or being stuck in traffic. Sure, these little things are annoying on your own, but you have to learn to remind yourself that in the long run, none of these things will really matter to you. Focus on the happiness of the bigger picture and learn to say, "Well, that wasn't great, but it's not going to ruin my mood!" It takes practice to be all zen and not let the outside world get to you. If you need time, take time to understand what happened, see how you can learn from it, and then move right on.
