Play for fun as often as you like, when the urge hits to try and push let it happen naturally, not every session will be your best session. Stop playing when unnatural pain starts to occur, like as if your body is telling you to chill out, seriously listen to your body.

If you have a strong desire to improve rapidly and want to push every session just keep in mind it's ok to play easier songs for fun still, and it will help with your accuracy. The key thing to take away from your sessions should typically be internalizing your improvement, taking note of if you tried something different like tapping keys lighter, or in a any way that increases performance. Set your own goals short and long term and you'll get to where you want to be with time.
