We all do it. We all waste time. Distractions, tasks that others can do for us, and things that lead to wasted blocks of time.
You don’t get more time than anyone else and it’s practically the only thing out there that you can’t buy more of. It’s also always being spent and there is no way to stop it.
So track your time. Write down and log every hour of your day as you go through the day (not after the fact! memory is not reliable when guesstimating the time we spent doing this or that.)
Find the tasks that you don’t need to do at all.
Find the tasks that you can give to other people.
Find the patterns that lead to time being wasted.
Organize your schedule to best squeeze the juice out of the hours you have.
Better to add work to your hours by better optimization, then try to add hours to your workday (usually done by foregoing sleep or family or other important things.)
What you don’t track and look at, you can’t adjust and get better at. I think it’s a good idea to track your use of time throughout the day.
