Fish

To be a fisherman you need the cool to not jerk your pole at the first sign of a fish and the endurance to not get tired of being in one place for a while.

Firstly you can't fish with your bare hands so you need to buy a fishing rod. Now that you have a rod you'll need some bait mostly anything will work even that piece of gum stuck to the bottom of your shoe. Now go to the water and fish what the hell are you doing here and not fishing!
