I have a few...
Sometimes we have to work at a job we don't enjoy in order to have the money to do the things we do enjoy.
More trouble often happens after midnight.
It can happen that being generous to someone sometimes results in them resenting you.
Don't do favors for people who aren't nice to you.
My favorite saying: Trouble with life is your half way through it before you realize it's a do it yourself thing.

When I was in my primary school my mother told me
Don’t break anyone’s heart, God lives there.

You can always learn something from someone

Don't expect a free ride through life!

Dead friends don’t snitch

Don’t sweat the small stuff

Never do unto other what you don't want others to do unto you



But it's also made me make other's feelings a priority :/

Take care of number 1 because no one else is going to.

You can be what you what you want to be.

Live life, don't let life live you.

Love everyone
Trust no one

Validate yourself.

Not my circus /not my monkeys

You probably waste a dime out of every dollar on foolish crap, so why not put it into retirement savings/investment for when you need it later?

Trust, but verify.

"if you do what you love you never work a day in your life"

"if someone says something about you that isn't true, why do you even care? And if it's true and you don't like it... change"

"You are not a victim. That suggests you aren't in control of your situation."

"Never wait for a man to get his shit together."

My father once said "if you take time to argue with every idiot you meet, you'll never have time to do anything else".
