An instructor is the person that needs to teach you. As an instructor, it sounds like you have very little stick time. You instructor needs to have you concentrate on flying the airplane first (airwork). Take-offs depend on what kind of plane you have - tricycle gear or a taildragger. Taildraggers can groundloop or snap during the takeoff (high departure angles that result in a stall). Do Not TRY this by yourself unless you want to lose the plane. I personally make my students master airwork first, then take-offs and finally landings.
