If you cant land on the runway you get a ditch, and if you cant stay on the runway there is no reason to land on the field at all, just land on any open spot..
But it seems like a common problem that people cannot land their airplanes, most people just belly land on the runway.
For take off: Be gentle on the throttle, stick back and counter w rudder.
Landing: Flaps out, manual trim, flare, stick back when on runway and gentle on rudder and brakes.
