In one sentence, describe what the following article is about:

The best way to have a fulfilling life is to spend your time doing things that you genuinely care about. Consider whether you are interested in art, science, politics, or the environment. Think about what you want your life's legacy to be. How do you want to impact the world around you? These questions will help you find the right career path for you.  Learn to distinguish between your hobbies and your bigger interests. Just because you like to play guitar, doesn't necessarily mean you should pursue music as a career. But if you eat, sleep and breathe guitar, then continue to practice and perfect your craft and pursue your dream. Don't give up on your hobbies. Just because your passion isn't lucrative, doesn't mean you can't or shouldn't partake in it. In fact, the opposite is true. Life is about learning to balance work and fun, and giving up either will be detrimental to your emotional health. Remember that if you have never worked at anything, you won't be able to appreciate the free time you have to partake in hobbies or spend time with friends. If you want to reach your full potential, you will have to devote time to strengthening the talents you already have, and uncovering any hidden talents that you haven't discovered yet.  Take classes or private lessons in subjects that you are interested in, even if you have no previous experience. You never know when that one elective will open the door to an entirely new career that you had never considered. Don't be discouraged if you realize that you are not skilled at something. Remember that even recognizing what you are not good at is still a step in the right direction, pointing you toward what you are good at. Once you have set your mind to doing something, follow through with it. Be prepared for obstacles, and don't expect immediate results. All good things take time and hard work, but it will be well worth it in the end when you achieve your goals. Remember that at the end of your life, you are much more likely to regret the things you didn't do than the things you did do. In life, you will undoubtedly come across people who will try to take advantage of you, whether it is financially or emotionally. While you should strive to be a sensitive, caring person on the one hand, you must also be tough-skinned and not let people walk all over you.  Be skeptical when people ask you to borrow money, constantly expect you to pay for things, or ask for favors without reciprocating. This person is probably taking advantage of you. Be vocal when something is bothering you. Whether it is your employer, your spouse, or your family member, you should get in the habit of calmly letting people know when they have crossed the line. You might be surprised to learn that this person had no idea that he or she was upsetting you.

Summary:
Identify your interests. Explore and develop your talents. Pursue your goals passionately and responsibly. Stand up for yourself.
