Yes, very bad. Wean thyself of such bad habits, and forgive thyself for being bad to your bimmer
Always place your left foot on the footrest to break that habit; don't ride the pedal. Don't be in a rush to get moving when the light turns green, let the bastards behind you wait- they're not gonna buy you a new clutch. In time, once you get the mechanics down, you'll get faster and faster at it.
