Nice Paolo...scare the guy shitless.....
Seriously, Paolo has a good point...you will know how far you should and should not push the envelope. First of all though, everyone has hit the nail squarely on the head here. Do not even worry about doing any tricks untill you can solidly ride down all of the runs in any condition and then do some off piste stuff. When you are ready to try stepping it up, start small and progress in a logical fashion at a reasonable pace. Speed management is the biggest key to your safety when trying new stuff. Build up slowly and master simple tasks before moving on to more complex ones.
Generally, the new rider will start trying small jumps that are on the side of the groomers, hit theses and become comfortable with getting a little air. learn the takeoff, flight and landing phase then hit things a little faster to get more air. Move gradually to larger features. learning to ollie is a great task to master as well as becoming proficient at switch riding at least for short distances to help with spins.
