That is good advice. 
But if you want fearlessness you oughta try what I did back when I was 10 years old. Went to sleep with my family in a tent up near Tok one night in early July.  Everybody lined their sleeping bags up side by side and I got the outside edge. I kind of woke up in the night and thought, 'Man, I'm so warm and cozy!' and went back to sleep. Next morning Dad went out and started the fire and put the coffee pot on. Stuck his head in the tent flap and said, "Say, did you know a grizzly was bedded down up against the tent last night?"
Well, I WAS fearless!
MY grandkids get a kick out of it when I tell them about the time I slept with a grizzly bear.
