Just back from the Gat Bash, so rather woozy -
Best thing I was told at the initial stages (and later as well) is that the aeroplane is designed to fly straight and level - let it! It requires a certain "leap of faith", but literally letting go of the controls entirely and allowing the aeroplane to fly itself usually works out much better than pushing and pulling it all over the sky! (Subject to caveats about trim, turbulence, & rudder trim etc.)
The trick is finding out how little you have to do, not how much.
Also, as an observation, not a criticism, you seem to be mentally preparing yourself for failure, rather than success!
