Also, don't forget your brakes! When you are clipping in, have full control of the bike and be ready to brake so it doesn't roll away before you are ready! When you unclip/stop make sure you are in control before you release the brake. If you focus, pay attention and have control of the bike, you will do fine! Also, try to get a pattern going where you always clip in starting with the same foot every time, and clip out on the opposite foot every time.
