I recently decided to not learn anything new right now. Instead, I made a list of all the songs I've learned and realized I've forgotten some parts of quite a few. So, I'm going to divide the list into 7 subsets, mostly organized by the tuning, and go through a daily rotation to "relearn" each to where I can confidently play them all.
That's my plan, but I know it's all about commitment to the task and that's often where i fall short.
