I do this thing where I feel like I have to finish tasks and projects in consecutive bouts of effort. But I'm working on developing a sustainable lifestyle where I do work incrementally--taking more frequent cycles of rest and work.
The older I get, the more I hear about the luxury of rest. I've met measured people who know themselves enough about how to avoid burnout and efficiently enjoy rest guilt-free.
This reminds me of the phenomena where people pick up new habits like a fad and hammer it. Think of the uptick in gym subscriptions in January. But you can exercise restraint and still push hard. "Patience in the process" is a phrase I've heard and am still endeavoring to live.
My partner is able to put a solid, quality three hours of studying per day and enjoy off-time watching games, relaxing, or working out. Another friend recently took a week off, post-thesis defense, even putting off the completion of his final projects to get a much-needed week of rest, listening to his body. Also, marathon runners excel even past their physical time because they get smarter and get great at pacing.
Maybe this is increasingly common knowledge, but rest can allow for more productive work in less time, and that's a discipline I need to build.
