[inopinatus]

1. Life is short and there's so much to do.

2. I'm building a business and I have competitors who want to take my market share.

Either of these two thoughts are enough to galvanise me. #2 in particular can snap me wide awake with blood pumping and ideas firing.

Ultimately I am guided by the principle of least regret, although I find that more useful as a decision making construct than a motivation tool.
