Thanks JW ! You made me feel much better

The dump happened during a left turn in my neighborhood. I was at a stopsign, obviously didn't give myself enough room to get going and make the left turn. I let my right hand role on the throttle, panicked a little, pulled in clutch and all brakes, didn't have enough room to stop before hitting the curb, and I dumped it.
So, any words of wisdom on starting from a stop when you immediately have to turn also?
