I was running a startup quite successfully for 5 years as a single founder, single executive from an environment without a startup ecosystem. I recruited and trained employees personally; productivity became a necessity and a habit.
Had to close the startup due to physical health problems, now that I'm rebuilding my life I guess productivity has become more important.
Of course productivity is important, but it isn't an end in itself. Neither are high incomes or appearences of success. If you are lonely and have to sacrifice your health you really have to start thinking about what it is all for.
I agree completely, I'm cautious about physical health now and doesn't trade it for anything. But, that has resulted in me having very little time for productive work and hence I'm in a situation where I need to optimise every bit for it.
