The magical quality of time is that there's 24 hours in a day, and 168 hours per week, and -- clever wording aside -- you cannot bank or defer that time. That time will come, and it's up to you to fill it up how you will, doing what you will, as well as you can, do to the things on this planet you want to do.
You thus reach a sort of axiomatic truth -- to deploy more of your time to some activity you think is important, you need to do less of something else.
Oh yes, you can ensure some activity gets done without your direct effort. You can do things more efficiently. Yes, yes, yes -- all of that is true.
And yet -- !
Still, it resolves to the basic equation: 24 per day, 168 per week, and there you are.
