You don’t have to go to college, but whether you do or not, I implore you to read. If you’re like me a slow reader, pace yourself but keep at it. Read bestsellers and classics. Fiction, biography, history, art, every damn thing. A big regret of my life is that I never tried to love reading as a kid. Do yourself a favor and carve out time to read every day. Even if’s it’s just a few pages. Your mind will sharpen and your heart will be full and your soul will be fed.
