Zachardy Wade Betz with some deep thoughts on how he’s most productive:

My high-level workflow looks something like this: identify the problem to solve; think on the problem and let ideas percolate; research, discuss, and experiment with these ideas; implement and test the solution; deliver and maintain the solution.

This cycle could repeat many times in a day. Or I could spend days stuck on a single cycle step. Every step in this cycle requires attention. The more attention I can devote, the more cycles I can complete, and the more productive I am.
