The world is not just sweetness.
It's a very mean and nasty place and no matter how tough you are, it will crush you to the ground if you let it.
Nothing will hit you harder than life.
It doesn't matter how hard you get hit, but how much you can endure and still move forward. This is victory!
If you know what you can do, do what you can do.
And if you are not who you want to be, don't blame others, that's what cowards do.
