Pruning
I am a curious person. I tend to extend my branches towards anything I find interesting.
I eventually reach a point where I don't have enough energy to sustain all those branches. That's the time to prune what it's not worth keeping. Sometimes the choice is obvious, sometimes it's not.
Pruning is an act of respect, respect for yourself. Focusing and directing your efforts means giving them value.
As you probably have read a thousands times: if you don't respect yourself, nobody else will. It's not always true, but some people have the tendency to try to squeeze out of you everything they can. Don't let them do that.
Cut branches that are draining your energy without giving fruits. Cut them with a firm hand.
