Focus more on solo.
Always go solo for a very long time before you wing man it.
You will have MUCH more experience/fun/results. When you wing man it after you go solo.
If you have to though, use wingmen every now and then.
Wingmen are like the extra ammo cheat in games (not infinite ammo). You'll learn how to beat the game, but you will have done it using extra ammo and will suck at beating it with normal ammo, next time you play it again you'll just keep being tempted to use your extra ammo cheat and will eventually cave and use your extra ammo cheat over and over again.
If you beat the game first, and play it again with the extra ammo cheat. You'll WHOOP ASS at the game, have a lot of fun doing it because it will be realy easy and fun to use it.
