A few ideas you can roll with depending on which you like best:
Don't navigate them. Take your fist and knock them all of the table, or throw them at your opponent.
Resign immediately every time there's a closed position.
Use a compass, sextant, or GPS.
Wear a captain's hat and say "ahoy!" to get yourself in the mood for navigating.
Don't ever let a closed position come up on the board ever again in your entire life.
I find it hard to navigate closed positions. Any tips?
