Don’t let “I’m not sure how” shot-block you.

Figure out how to get it done.  Read.  Study.  Listen.  Interview people who are already knocking it out of the park.

Imitate a hero.

Or innovate, create, and forge a new path.

But if you know what you’re supposed to do, don’t let “I’m not sure how” get in your way.  There’s a way to get that thing done.

Raise the money.  Recruit the volunteers.  Cast the vision until you’re blue in the face.

But don’t get shot-blocked.  “I’m not sure how” is a lame excuse.
