With exquisite timing, I started getting up half an hour earlier to go to work this week--at the same time we set the clocks forward an hour for daylight saving time. So effectively I've been getting up an hour and a half earlier each morning.
Tonight, at sparring, I was exhausted. I was also feeling very defensive, at least when facing black belts, due to my stunning encounter with a right cross last week. I did fine against some of my opponents, but against a couple of experienced black belts and a brown belt, I was making real rookie mistakes--things I thought I'd fixed a long time ago.
I'm going to bed.
