I can work 8+ hours up to a few weeks in certain intense situations where: (A) I feel like I’m making good progress (B) I like the work (C) the work has a meaningful (not BS) near term deadline or milestone to achieve that I care about (D) few personal obligations prevent me from working as much as I can Cases I’ve faced this include: - writing chapters of a book - solving a really interesting and foundational problem for my team - creating a much needed open source tool I really believe needs to exist - real customers that really rely on my software need a fix / support After working intensely, I will switch to a few weeks of low effort work, and not be as productive, and being a slacker for a while. My mind needs to recharge... Generally I do pretty poor with a consistent 40 hrs, and instead oscillate between high and low energy times.
