I like "if you hang around a barbershop long enough, you'll end up getting a haircut" meaning, if you hang around a certain type of person long enough, they'll impact you eventually. ThriftAllDay

HAHAHAHA.....

If you can laugh at yourself, you'll always have something to laugh about.

Don't remember who told me that, don't know if they were quoting someone, but it stuck. roberto10992

Also it's good because it's hard to get bullied because you learn to just laugh it off. The more you don't care, the harder it is to be hurt emotionally at least. Uh_bruj

Not for Everyone....

When I was really young, my father told me this gem, when I was upset about being teased at school: "No matter how nice and kind you are; there are always going to be people who don't like you or appreciate what you do." I forget if there was anything else he added afterward.

It does sound pessimistic, however I internalized it as, to continuing being kind, and not letting a harsh response or cruel treatment bring me down.I think my dad was trying to teach me not to put too much worth into how much worth others put on me, but focus on my own self worth. Ultimately, in my own perspective, it did help me keep a positive attitude on life.

And then there's you...

A smart man learns from his own mistakes, a wise man learns from the mistakes of others. Luck is where preparation meets opportunity. RickySlayer9

I use this one a lot in a professional setting, but my take on it is this:

"A smart person learns from their mistakes.

A wise person learns from others'.

Prep.....

Lack of preparation on your part doesn't call for an emergency on mine. kj_SmrtAlc

Humans are inherently self serving. I can't remember where I heard it but I've never forgotten it. Whether one sees this as a good or bad thing says a decent amount about them. Which_Hedgehog
