Am I My Own Weakest Link?

I've been thinking a lot lately about life, the big decisions, the big picture, and it occurs to me that I appear to be basing my overall wellbeing on my poor choices. We're all familiar with the saying "you're only as strong as your weakest link" well I'm feeling only as productive as my least-productive days, only as smart as my poorest decisions. While I can see the logic in the weakest-link analogy, I need a more positive perspective. I need to be strong despite my weakest link, strong enough to fix my weak links. (Seems I can't blog properly from behind this Navy firewall, I'll edit later to add the image I wanted to put here.)
