I'm extremely thick skinned, but I have a soft spot for puppies, romance, candlelit dinners, long walks on the beach, and I cried at the end of The Bridges of Madison County.
I've also been in a lot of fistfights, some with intent to kill. I've been shot twice, had my hand slashed in a knife fight, and know how to use damned near every weapon there is. I've had sniper training, all sorts of survival training, and once worked for a P.I. I've lived in the deep woods, walked across wilderness alone, and done more than my share of dangerous, and stupid, things.
But whatever I'm doing, I try to keep my emotions in control, at least outwardly. It does no good to let your feelings get hurt easily, and it does no good to throw tantrums or to get angry when anger doesn't help.
But be yourself. None of us is one person, we're all a dozen people rolled into one. Just don't let your emotions rule you. You need to rule them instead.
