Genghis is right. A slow and steady progression is best.
Go through the manual or any other guides you can get your hands on and get the speeds for take-off/climb and landing locked into your mind. Finals is not a time to try to read the book (or the placard)
Spend a lot of time in the cockpit getting the feel of the controls and get to know where the key controls are.
Practice taxying and a few straight runs at almost take-off speed to see how it behaves. Then on a quiet, but not windless, day give it a good go.
