This is brilliant, and really taps into the way I run my business. If I might humbly add two more points...
The first is, don't think that getting a team is an answer to anything. It might work, it might not, but you'll spend a huge amount of time and psychic energy managing them, solving their queries and problems, and generally acting as their shrink/nurse/mother.
Second, and more important is, don't ever beat yourself up for having low energy days (or for not getting through the whole "to do" list on those days !). Don't let anyone else beat you up for it either. You are the boss, they aren't, and they can never walk in your shoes to understand what you have to deal with or why you set the rules you do and work the way you do. I have this, with customers who ring up at 9am, when I have realised that my natural cycle is to wake up at 10am, work until 5pm, nap for a few hours, and then work again between midnight and 2-3am.
Glad aspects of it resonated with you @alonicus. Thanks for the kind words.
