If you can measure it, you can manage it. That's why I have an Apple Watch. There's data in my everyday life I want to capture, and that I want to manage.
Note, though, that I said nothing about time. I don't much care about time anymore (not that I'll ever be late if I can help it...)
Time is a human concept that more often than not makes us dwell on what has happened, or worry about what will happen.
Don't manage that. Let it go.
Keep yourself in the here and now, and focus on this moment.
That said, take what you learn from this moment and do something with it.
