My tip: tie good knots.
Use spit to avoid burning the line. There are times when you are in a hurry, or your hands are cold, or you're lazy, and don't want to pay attention to the particulars. Take the extra few seconds to do it right. And if it's not, cut it and retie. If you aren't sure about the knot, look it up on the interweb and practice at home.
Find knots that work for you. Here are mine:
Egg loop- for the hook
Palomar- for swivels and lures. (Doubled Palomar for braid)
Trilene- for any other areas or if my fingers aren't working the Palomar correctly (e.g., cold)
Double uni- for mono to mono
FG- for braid to mono or fluorocarbon
And yes, you CAN tie these! My hands are pretty big, and all it takes me is time and good directions. If you're on the water and have a brain fart, don't be afraid to ask for help, with knots or anything else. And if you really bing it up, then have a good laugh at your expense. It's supposed to be fun, right?
Good luck, be patient with yourself, and enjoy the moments!
