Capacity
You want to do all the things all the time.
You are capable of doing some of the things one at a time.
In theory, you understand this distinction; in practice, you habitually underestimate and overcommit.
Sometimes you simply are very busy and external uncontrollable variables emerge.
Most of the time you have estimated ineffectively; this is an internal variable.
If you frequently find that you accomplish less in a day than you want, it is a capacity estimation issue.
Your brain defaults to finding external reasons for why things do not happen.
Internal variables affecting capacity are equally important, and more controllable, to external.
When you are unable to do everything you want to do, the most likely variable to examine is your internal estimation of capacity.
If multitasking, zero margin for error scheduling, or time travel are central to your estimation for capacity, do not look externally when you fail.
