RegFlyer:

Take your time to learn first skills first, and properly.

It is very diificult to re-learn something that was learned wrongly in the first place; hence, avoid that.

The more you develop reflexes by flying very high and correcting mistakes yourself, the better prepared you will be to learn maneuvers like take-off and landing, that will create higher danger and fear of ruining your model due to normal mistakes.

Be honest to your instructor, if you feel you are not ready for the next step.

You can also make the practice in FMS more real, by using wind and gusts, in different directions and speeds.
