Ive been thinking about this for a little while: it’s very very very important to be very clear on what is most important to you, or a heirarchy of the importance of things to you. You don’t have to tell anyone, but just know it. When you do, you’ll know what to fight for and what to let go.
Those who have known me for a bit know that I used to be a lot feistier (is that a word? or did I just make that up?), and I’ll get upset at most of the things that rubbed me the wrong way no matter how small (in fact, I used to get most upset at the smallest things!). Whether or not I said something to the other party is a different conversation, but either way, I’d act how I was feeling: salty. As I’ve grown older I’ve learned that I have to pick my battles very carefully and let some things go – make excuses for the other party if I must and be kind (not for them, for me). That way, when I insist on something or complain about something, people take it very seriously.
