It's almost indescribable isn't it? Things don't necessarily have to be in order in your life, but it's okay. They're just good enough that you can still smile and laugh, and maybe even love. It's knowing all the wrong things in your life but not focusing on them. It's like pushing the drama behind you and pulling that smile out front. It's not a fake front and secretly being miserable inside. No.
It's dealing with all the crap in your life first, so you can enjoy being happy, really happy afterwards. You've got to cry to be able to appreciate a smile. There's no easy path to happiness. But when you reach it, not a million words can describe the feeling.
