Keep my foot clipped in at any cost.

It's 10 times harder to get going while trying to clip your foot in, and usually the more you struggle to get your foot in while getting up to speed, the less likely the pedal and cleat are to successfully engage. I won't give up and unclip until I have no choice. It helps a lot to be able to see the lights changing so I don't unclip just as it changes. That is definitely one of my pet peeves.
