If the "Touch" wasn't good, don't do the "Go".

What I mean is - imagine you're crossing a river by stepping on stones; You plan to put your right foot on stone "A" and then step over to stone "B" with your left foot. But once you step on stone "A"A, you find that it's wobbly, or slick, or whatever. Instead of continuing to stone "B", you would instinctively put your left foot down on stone "A" to regain your balance.

A touch and go is similar. Plan to LAND. If the landing goes well, reapply power and go around again.

If the landing doesn't go well, stop, turn around, taxi back, take off and try again.
