Avoid energy suckers. If you think you need to try to be nice to everyone, ask if you would be nice to a rattlesnake or a thief, or a cheat. Energy suckers take the air out of a room and leave you depleted. Abandon them, don’t invite them, move away from them. You have no obligation to be hurt or even inconvenienced.
Mindset: Some people are natural “takers.” Don’t enable them by constantly giving.
