I’ve been thinking about this on and off a lot these past years.
I think part of it is that when your time has no value, nothing you choose to do is a waste.
That’s not to suggest your time needs to be worth nothing. But that you stop perceiving your time as having intrinsic value. My kids succeed where I fail all the time. They’ll spend hours on projects that have been done far better by other people already. But they just don’t think about those facts. They’re not relevant. Their time is not being valued in anything other than the feeling of “I want to do this thing.”
