A big salary can evaporate quickly. Hundreds of thousands of American aerospace engineers laid off in the 1970s discovered this. The ones who’d toiled in obscurity on “landing gear bolt #39” ended up as cab drivers or greeters at Walmart. A personal professional reputaton, by contrast, is a bit harder to build than the big salary but also harder to lose. If you don’t invest some time in writing (prose, not code), however, you’ll never have any reputation outside your immediate circle of colleagues, who themselves may end up working at McDonald’s and be unable to help you get an engineering job during a recession.
I need to pay more attention to this. It is excellent advice.
