1. Saying no.
I used to say yes whenever somebody needed me or needed something from me. After going through a few events where I desperately needed somebody to be there for me in the same way (and nobody was), I realized running myself until I’m dead tired trying help and please others isn’t worth it.
I don’t have to hang out with people I don’t want to. I don’t have to rearrange my schedule to swap a shift with my coworker who has poor life planning skills. I don’t have to pet sit for you even though you know I have nothing else going on that weekend. Last but not least, I’m not going to be a last minute add on to your vacation because your other friend backed out and you can’t find somebody else to go.
No excuses necessary, the word “no” is enough. People act like this is some mind boggling thing and it’s somehow rude.
2. Thinking about yourself first. You’re no good to others if you aren’t good to yourself.
3. Cutting off toxic family members/in-laws. I have cut my narcissistic abusive sister out of my life and I am in the process of cutting off my mother-in-law. Life is too short to allow abuse into your life because your abuser is a family member.
