We learn through experience and a lot of what we know comes from troubling times.
This post isn't about book knowledge, but rather it's about the knowledge of life.
We go through hard times in order for life to teach us what we want and don't want... basically we go through the school of life, where we have to apply our knowledge of past incidences to not make bigger, greater mistakes.
We learn the hardest lesson on – love, money, friendship, our families and lastly, our careers. We go through life trying to win literally at life and sometimes we seriously fail at it.
We learn about love through the mistakes we make with love. We learn through the emotions of happiness and pain. When we feel joy, we want to continue that feeling,
If we learn that we don't like something, we have to learn how to change it, this is in all aspects of our lives, it's not just subject to one.
This knowledge is useless of we don't apply and we will just continue to dig ourselves a deeper hole.
