Your progress might seem small; it might be exponential. But, the important thing is that you're making progress. You're putting in the time and effort to better your life, no matter what form that improvement might take. Always remember that you're doing great and progressing at a pace that suits you.
Learn a new language, acquire a new skill, make a fun craft, etc. But, it's okay if you don't feel up to doing any of that. It's fine to just want to rest and relax. You don't have to focus solely on being productive or creative. This is your time, and you should use it however you want to.
