There’s nothing noble about diminishing yourself to support others. You can’t help someone from a place of lack and resentment.
Prioritizing yourself and being the best you never has to be at anyone’s expense. It’s not a zero-sum game.
When you put yourself first and take care of your needs, that’s when you have more to share and extend to others.
No one has to lose for you to win.
No one has to have less for you to experience abundance.
No one has to suffer for you to feel joy.
If someone is threatened by you prioritizing yourself, that doesn't mean you have to do something about it or change your priorities. You can decide whether you want to keep around people who benefit from you dismissing your needs.
