A key to being happy is to be yourself. Put yourself in the right lightning. Solve problems, make art, think deeply. Love is essential, gregariousness is optional. Spend your free time as you like it, not the way you think you are suppose to spend it. Be yourself. Establish for yourself who are you, what makes you tick. Do that. Find what you love, and then do that. What is your art? How do you find energy? Live a life where you are comfortable, you work according to what lies within. A life where you are you, not an idealized person you think you should be.
