His entire life is full of amazing stories like that. And he never, ever, brags about it.
Everything he actually 'boasts' about is for show, part of his negotiation tactic. Usually directly related to a deal he is trying to push. All the wonderful humanizing things he has done that he could brag about, he never even brings up.
For all of his boasting he is actually a pretty humble dude where it counts.
The story between him and Trump is fantastic.
Trump gave him a loan with interest when no one else would, when Johnson came back to repay, Trump tore up the check and said "Go run your business"
