Keeper Fantasy Leagues:
1) Limit the leagues you are in. This will allow you to concentrate more on certain teams. Making you more competitive
2) Know the rules. Nothing is more embarrassing when you don't. For example you max out the number of moves your team can make without realizing there is a limit.
3) Take the time to make sure you can enter and draft your team. Waiting until the last minute can spell disaster for your team.
