The way to do anything that maybe takes a challenge is to go at it with instinct and intensity. Release your inner piranha. Making love, decimating an enemy (like in sports), train yourself to the end and chow down.
How to do anything involving a weapon, let's say, make it part of your hand. Like David and the rock he flung at Goliath. When it leaves your hand, it's still in your hand all the way to the giant's forehead. Inner Piranha, away!
