I’m a teacher who came out of retirement for this school year, so my practices have not been the most consistent; however, I will say that when I do practice, I make sure I progress in something.  Everything I knew is coming back and at the same time, I’m getting faster.  If I miss a day, I practice more the next time I pick up the guitar.  I revisit all of the lessons everyday as a warmup, then I practice one or more songs that I want to learn.  The progression is improving.  I can already tell by the speed at which I transition through chords or picking scales.  Come the end of May, I’ll be back into retirement, so more time to practice!
