Productivity hack - For me, it’s mostly a single word - planning. I wasn’t always good at it, definitely not yet a “master” of it, but breaking that proverbial elephant up into smaller pieces, and organizing a plan of action for dealing with them is the #1 productivity “hack” for me. Sorry that it’s not an actual shortcut, or anything…I personally don’t believe in those anymore. Complementary habits to this are thoroughly commenting code, having descriptive commit messages, file names, and variable names, maintaining documentation. Use that Readme.md. This is true of any project, even if I’m the only developer - never underestimate your own ability to totally forget shit.
