there is something we will never understand/control

people tend to like something they can control, that's why people like easy task. for the difficult task, people find it challenging, but eventually get it under control and feel proud of it.

however, there is something that we will never gain the control of... may never be able to understand it.

i used to think i understand it, because i try to be understanding and nice for all my life.
the result is disappointing.
now that i don't even try to understand or waste time to try to get a control of it.

if it is not controllable / understandable, why waste time?
i know it hurts, i understand it more than anyone else.
but i still want my friends to be happy.
don't do something you would regret, just do what you can.
