Cutting down warmup time?

Still not having much luck getting over the "hump", but I think I'm getting to it more consistently. I have kind of a routine, but the results aren't regular. Like the "window of opportunity" before thoughts of "This isn't working" show up, it closes sooner some times than it does for other times. Some times it doesn't open at all. It would be helpful to cut down the time it takes to get from zero to cruising speed, and to get there before self-doubt sets in and ruins everything.

Maybe some kind of aphrodisiac or vitamin? Even if I don't get to where I need to be faster, anything that would keep it a smooth ride the whole way through would be a great help. Anyone know of anything?
