Don't dwell on how rough it might be up there otherwise you won't go. When I get into the air, as soon as I stop crying I concentrate on the task at hand, that is, the navigation. (I use map and compass, not ipads etc.). By doing the 'real' pilot stuff you tend to forget about the bumps and wing rocking, that is, until you're back in the circuit where the crying starts again. Having said that, I do avoid hot days or windy days.
