When it comes to planning, you want to have every aspect covered as best you could.

However, before you act on that information, have an outsider examine your plans.

Planning a road trip with a couple friends?

Assign someone the job of “tenth man.”

Getting ready to make a big life decision?

Ask someone you trust to be your personal “tenth man” and poke holes in it.

Effective planning comes down to strategy and reiteration.

Keep finding and plugging holes until your plan is rock solid.
