What's the best way to put "blinders" on in life and have "tunnel vision" and just focus on your mission and not DWELL on it when people (1) insult you or (2) ghost you?

I'm a bit "neurotic" in that I dwell on things.

I let things bug me.

One teacher even told me back in elementary school, "Hopeful, you're so buggable."

You have to purge your brain of everything that's not useful and everything that's distracting from your mission.

For example, this one "friend" just ghosted me (not real friend), and she got the last word, and I can't stop dwelling on it.

It's crucial for success that you make that shit take up minimal bandwidth in your brain.
