Follow your passions and your dreams. Do what you love doing. Think of the type of people you love and care for and what you love doing for, providing for, or making for them. 

If you haven't found anything you love doing, try new things. Eventually you will find something you love.

There was a boy in middle school who was on drugs and was failing most of his classes. He was always in trouble and most my classmates stayed away from him for fear of the type of dangerous people he attracted through his choices to do drugs and drink underage. In art class, our assignment was to draw your hand. The art teacher gave no instruction. It was a 'before and after' experiment. That boy who seemingly was a failure in every way to everyone, flawlessly, effortlessly drew his hand and it was so realistic and perfect no one could believe it, not the art teacher. Everyone was surprised, but not as surprised as the boy was. He had no idea he had that extremely rare talent. That day, because of art class, he discovered his purpose and talent. Everyone in the room looked up to him in awe and envy. Yes, the boy who everyone incorrectly perceived as a total failure, was the only one in the school who could perfect draw the most difficult part of the body. He had no instruction,  no practice and no training. He effortlessly did it. 

I will never forget that boy. From then on, I knew everyone has a talent no one else has, and everyone has a purpose. Everyone was given gifts at birth. 

You may not know or believe you can do something amazing, but I believe it. Your creator believes it. Because He is the one who blessed you with it. 

Go out and try new things. Have fun, knowing that if you hate doing something, (other than paying bills and taking a shower) you dont have to do it, because its not your purpose.
