What's your best life lesson?

well said

my biggest lesson in life is to trust people, very often people let people down

Don’t take it for granted. Don’t take anyone for granted either.

I'm not really sure if its a life lesson per say, but my Grandma always told me not to worry about things I cannot impact. I tend to stress and worry about things out of my control to an almost unhealthy degree.

Through time I have learned a few life lessons and 1 of them was when you have to be careful who you trust in life, you will see the people who are there for the show and you'll see those who are lurking in the darkness but when it comes down to see who you can trust 90% of those you thought are 100% will eventually turn out to be 0% 

You won't be satisfied till you try it your way.

@tommy  One of the most important lessons for someone who has been raised by people who treated them poorly...

It's not your fault.  

They didn't treat you badly because of how you were, they treated you badly because of how they were.  No child deserves to be treated badly.  You didn't cause their coldness, and you cannot fix their coldness (or anyone else's).  

I believe one of the core issues we face is that we are raised in cultures that teach us to believe all parents love their kids.  Phrases like "a face only a mother could love" suggest that Mom will love us even if no one else will.  The message is unarticulated, but powerful: if your parents can't love you, no one can.  It's also a suggestion that if your parents don't accept you, it's because there is something very wrong with you. 

But some people just aren't cut out to be parents.  They aren't loving, and maybe they don't have much of a capacity to love, but they have children nonetheless.  It's not the fault of the children.  As adults, we need to stop blaming ourselves and start realizing that we didn't do anything to make Mom and Dad (or Grandma or whoever) treat us poorly.  They were supposed to love us unconditionally.  The fact that they didn't is their flaw.  We were just kids looking for love from people who couldn't or wouldn't give it.

Lots of great wisdom in this thread! Thank you @tommy for compiling it all :)

Very true.

@tommy My life lesson right now is "Never blame anyone in life. The good people give you happiness. The worst people give you a lesson. The best people give you memories." I am glad for the people who bring me happiness and positivity. They make my day when I am down. I don't blame the worst people because if that event or situation didn't happen I wouldn't have learned from it. I thank the best people for giving me memories that I will never forget.
