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.
