Don't brag about tomorrow,
since you don't know what the day will bring

Let someone else praise you,
not your own mouth--
a stranger, not your own lips.
~Proverbs 27:1-2 (NLT)

Here's a question... What feels better?

Boasting of your genuine accomplishments

or

Living such that others boast about your accomplishments

I think what’s better most definitely is to praise others rather than yourself.
