Admit it, we all make mistakes. The hardest part of being a human is you must decide what's good and what's not because whatever your decision may be, it'll change who and what you are in the future. So, making decisions must be taken seriously but sometimes we jump off the fence by choosing to do the wrong thing. Even if you know your decision isn't good, you still make it anyway. To quote Lily Aldrin of HIMYM:
"There are certain things in life where you know its a mistake but you don't really know it's a mistake because the only way to really know it's a mistake is to make the mistake, and look back, and say, "Yep. That was a mistake." So, really, the bigger mistake would be to not make the mistake, because then you go your whole life not really knowing if something is a mistake or not." - Season 1, Episode 21, HIMYM.
Word! Sometimes its the society that's fucked up. They tell us this is bad so we must choose this, we must be this and we must act like this. Blah, blah, blah. The same idea, the same shit. Why don't we go out of the box and decide for ourselves. Besides, we're not living for the society, we are living for our selves. You know what sucks? When you choose to make the odd decision and you failed, then the people around you are saying you are a failure. So what if they see you as a failure, you are not living for them. If its a mistake then its a mistake at least you learned and have experienced the down side of life.
