Hey Joe, It is pretty much up to you how you want your jade to look. Here are a couple photos of my jade. Some people do even more pruning than I did. I'm sure you will see that when they post their photos.

Before:

Here is the after photo. I would have cut it down a bit more but it is almost ready to flower so I wanted preserve some of the flowers and will even it out on top once it is through flowering.

Good luck with pruning your jade.

Joe,
