In reality, the world will eat you, swallow you whole, and people in the end won't care about you. That's true. It's about a battle in life, sometimes you have your weapons, sometimes you don't. And most of the time it's unfair, but it's all about how will you take it. You always have a choice, and you can never ran out of it, but most of the time none of the choices are your preference. At one point in your life you will just be one of the victims of fate. And it's important to be clever, sometimes you even have to cheat yourself, because if you don't the world will loose you. You will be lost in the game, and you will see people winning behind your back. And you wouldn't want that. As long as you see a tiny bit of you saying "you can" then you have to keep up the fight no matter what.
There could be bad and unfortunate things along the way, and that keeps your life realistic. Everything can't be that good and perfect or instant in one's existence. If life is as easy as that, then no one will be working their socks off just to be where they want. You must know what you want and make a goal in getting it. It's just that, in reality I strongly think that bad things are more likely to happen than the good ones, and everyday is a test on how strong you are, how persistent you are to win, no matter what about and how hard it is. Either way, the world knows how to reward, and you will wake up one day feeling forever grateful 'cause you never give up with reality.
