You have this one life. You can choose to grow up or not. I never want to grow up. Always stay childlike but not childish. That way you will always love life, love the world, always want to find out more and not lust after something that a hundred billion sperms and a million eggs never got the opportunity to sample, because the one sperm and one egg that got there first to make you kicked all the others into touch. Carpe diem and stop whingeing. You're a winner.
