The arrogance examples you used were funny, I use a similar method as you lmao in that I push myself with motivating words and thoughts, and thinking highly of myself. This is not to actually become that made-up grand person in my head, it is very clearly fiction, but telling those stories gives you purpose- especially if you’re someone who feels unstable in their own selves and unsure. Doing that in the past has helped me get a grip of myself, and now I can better recognise all the blessings I have in my life already, to be grateful for and to jump on the opportunity to prove that gratitude by being modest and helpful to others. So yea, I dunno if this relates to u or
