My mother used to tell me that my eyes were bigger than my stomach when I took food more food than I could eat. I have the same problem with MOOCs. The future me always has more time, is always more dedicated to learning, is always more focused. So I sign up, and when the class starts I'm no longer the better, stronger, faster, future, me, I'm just me. Still I manage to finish some, and learn a little from the ones that I drop, so I don't see it as a problem.
