1. Warm up properly
2. Relax - if you ever feel tension then stop and relax yourself.
3. Record yourself if you can - it will help to put into perspective what you are playing
4. Record your progress using a notebook
5. Practice with a metronome.
Yup thats a propper shopping list of things to do but its worth getting into those habbits. You'll really benefit from them. Hope it helps!
