To improve your jazz piano systems in different categories so you can develop progressive consistency, that will reward you for the rest of your jazz piano career.

Focus on the categories that you think you need most help with. There may be areas that are lacking which are effecting other areas as well. For example, the solo piano category will essentially effect ALL aspects of solo piano, whether it be harmony, rhythm, reharms etc. 

These systems will be used over and over and over again in your jazz piano playing. The pros use them, I use them, and the more you can integrate them, the better you will be.
