Sometimes.

Sometimes you just need to give yourself some slack. Sometimes you are going to make a stupid decision. Sometimes you'll make the same mistake twice. Sometimes you won't get the grade you want. Sometimes life is hard and kicks you while your down. Sometimes you are lonely and wonder why. Sometimes things aren't fair.
BUT...
Sometimes life is fabulous. Sometimes everything works out as planned. Sometimes you'll catch a lucky break. Sometimes you'll feel like everyone in the world loves you. Sometimes your day will seem to be straight out of a movie. Sometimes you will see the true beauty of the world. Sometimes you just want to sing as loud as you can. Sometimes you can't help by smile.
All the times we need to say thank you for the hard times so we can notice the great times.
