This stands true for me since i've shut down from people, i feel more confident without their negative vibes bringing me down. I was tired of being excluded, and looked down on all while being friendly, polite, & supportive. I'm much more confident now. Self respect has taken away the insecurities. I'm also getting a very sharp intuition as i get older that i listen very closely to.
AMEN! That done in secret is blessed by God. Don't cancel it out by seeking a blessing (i.e. attention or praise) from mere humans.
