Smiling is a simple way to completely transform the energy you give off to others. By giving a smile, you'll look more approachable, and you'll even feel happier. Try smiling more often to show that you're confident and friendly. Smiling politely to people you interact with throughout the day, such as the cashier at the grocery store or the receptionist at your doctor's office, is a great way to show your kindness. The way you carry yourself tells other people a lot about how you feel, so make sure you're communicating confidence. Avoid looking at the ground when you're standing or walking around and hold your head high. If seated, sit up tall with your shoulders back and relaxed. Practice walking with poise by avoiding dragging your feet or hunching over. If you're constantly worried about your flaws, it will show in how you present yourself to the world. Try to focus on the aspects of yourself that you love, whether it's something about your looks or your personality, and put any negative feelings aside. Try saying what you like best about yourself when standing in front of the mirror. Try to spend 30 minutes each day doing some form of exercise, whether it's going to the gym, playing a sport, or even just taking a walk. Not only will exercising keep your body healthy and fit, but the endorphins will have you feeling happier and more confident.  Work out with a friend to keep you feeling motivated. Try playing sports like volleyball, basketball, tennis, or swimming. This doesn't mean you need to tell jokes all the time, but try to let loose a little and avoid taking things out of your control too seriously. If you're able to laugh off things that go wrong, others will be attracted to your ability to go with the flow. Making someone laugh is a great way to ease any tension and make you more attractive, whether it's through a joke or just a funny comment.
