I’ve read something that reminded me of this, and I think it’s a good place to start.
1- boundaries are good, they’re your friend
2- decide what your core values are
3- you cannot change others, so change yourself
4- decide the consequences ahead of time
5- let your behaviour, not your words speak for you
6- say what you mean, mean what you say
They are pretty self explanatory, specially for me. I used to write down philosophies in life and I know deep inside, I still have many of them down. I need to start doing that again, I want to start doing that again.
