My focus and my energy are positively out of whack.

Here are a couple of axes:

1. Socialize vs. Isolate - I cycle rapidly between wanting to connect
  with people, and canceling social engagements.

2. Physical activity vs. Torpor - My physical activity is generally
  up. Pre-covid most of my physical activity consisted of gentle
  activities like yoga. Now, I go out for a run almost every day
  because I have more explosive kinetic energy. But even then, I
  cycle rapidly between craving movement and feeling too unmotivated
  to get up out of my chair.

3. Hunger - for the most part, I have no problem maintaining my
  intermittent fasting routine. If anything, it's easier at home
  than it was in the office because there's not an abundance of
  office snacks everywhere. But sometimes my hunger is high and my
  discipline is low, and I break my fast early.

4. Focus vs. Distractability - this one is huge. I can't seem to
  focus on any one thing. My productivity is abysmal and I can't
  seem to get things done. Things to try: A) strict adherence to the
  Pomodoro Technique. B) more meditation practice

5. Work Life Balance vs. Work Life Integration: I feel like I have no
  time to do anything besides work because work is expanding to fill
  all of my personal time. There's some kind of faulty logic happening
  that is integrating work into my life to the extent that I never
  stop working. If I'm home all the time, and I work from home, then
  I can work all the time! The math supports it! Thing to try:
  strict "clock in" and "clock out" times

My sleep routine is a little bit off too. Staying up a little later
than I usually do. I just need to be more disciplined about that.

I guess that's the problem. I'm not feeling very disciplined or
focussed right now.
