This clock change is very inconsiderate. For weeks (probably until it springs forward) I'll be awakening (against my will) at 4:30. If I hop out of bed then my internal alarm will remain fused to that schedule, so I must remain under the covers until my brain catches up with the rest of the world.
Yet what to do under there? Perfect opportunity to focus on a shiur.
Earlier this week, I tuned into this fascinating one by Rabbi Daniel Glatstein (I had heard it last year, but my recall isn't as sharp as it used to be). It's a fun listen, but for those (singles) who are short on time, the last few minutes (at the 50 min mark) are a pleasant boost.
