5 Life Lessons Everyone Needs To Learn Before They're 30
Understand you can't please everyone.
Not everyone is going to always agree with you. You don't have to go out of your way to conform to what others want from you. Don't seek validation from others.
Let that come from within. Stick to your guns, have an opinion, and assert yourself.
Keep yourself in good health.
Your teens and 20's is the right time to keep yourself in good physical condition.
Think of it as the foundation for the rest of your life. The better you eat and the more you exercise as a young person, the better your health will be later in life.
