Congratulations! You've made some changes to your work/life/tools/thinking/way of existing and you're getting more done in less time than you used to. You can grade a little quicker, write a little faster, submit things a little bit sooner.
Or, if you're not quite there yet, imagine that I have gifted you five extra hours in every week moving forward.
How would you spend them?
No really, imagine how you'd spend them.
When I did this exercise for myself, I came up with three work projects I have been struggling to get launched. Did you say something related to your work as well?
Now, there's nothing inherently wrong with being more efficient at work things so you can work more.
There is a problem when you have internalized the idea that the only worthwhile use of your time is working.
So as you explore ways to be more focused, schedule better, plan more efficiently, and work smarter, also turn a critical eye to where you start to spend some of that newly freed up time. Are you doing the things that fulfill you, that advance you, that enrich you, that line up with what you value, what you find important? And if not, why is that?
