Fear is not an option. Luck is not a factor. The only question in this life is whether you will knuckle up or knuckle under. Failure lies not in getting knocked on your ass, but in not ever getting back up. No matter what you've been told, it's not what, or even who you know (or blow) but how hard you are willing to grow.
And always remember to be good to you, to take care of you. You are the only you those fortunate enough to know you have in their worlds. And even if you don't see them yet, someone, somewhere, is relying on you to take care of you and stick around to be there for them when they finally find their way home to you. And if you haven't been good to you, then you won't be able to be good to them when they need you to.
