Do you know where you are, where you're going, and how you'll get there? Are you certain?
Is the pull of the destination so strong that reaching it is a foregone conclusion? Is that guaranteed?
How will you deal with the naysayers, the negativists, those who cannot see what you do? Will relationships survive?
What happens when the path is unclear, forked, or replete with obstacles? How strong is your resolve?
And what if, HEAVENS NO, something changes?
