The world really is mine, and I can turn it into whatever I want.
I know if I'm sad it's my fault because I can think of a million other things that make me happy.
I think therefore I am?
I am awesome, and it shows.
It's true - people who are happy don't somehow have better lives than the rest of us. Nobody is immune from heartbreak and tragedy, but the ingredients for happiness also exist in all our lives. Everyone gets blue from time-to-time, but remembering the content of this post should serve you very well in the future.
