Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.
Hard days are the best because that's when champions are made.
Don't practice until you get it right. Practice until you can't get it wrong.
You have to remember that the hard days are what make you stronger. The bad days make you realize what a good day is.
The more you talk about it, rehash it, rethink it, cross-analyze it, debate it, respond to it, get paranoid about it, compete with it, complain about it, immortalize it, cry over it, kick it, defame it, stalk it, gossip about it, pray over it, put it down or dissect its motives it continues to rot in your brain. It is dead. It is over. It is gone. It is done. It is time to bury it because it is smelling up your life and no one wants to be near your rotted corpse of memories and decaying attitude. Be the funeral director of your life and bury that thing!
Life goes on. Get over it. Be happy anyway.
