In the book Deep Work, the author talks about the fact that there are several reasons to perform deep work. One (under-appreciated) reason to work deeply is that, in working deeply, you build up the stamina and ability to work deeply. The act begets the act.
I feel the same way about blogging each weekday based on a simple prompt: what is something that I noticed today? By writing about what I notice, I build up the capacity to notice. The noticing muscle gets stronger. Not necessarily better, but stronger. The act begets the act.
