Gray hair helps. I’ve got enough experience at this point where I can be productive without going into “production frenzy.” Lots of the younger folks don’t get that yet and think it’s all about how much code you write or how long you’re at your desk. I like to think of it as the difference between doing work vs “producing evidence of having done work.” There is a lot of pressure to do the latter I think, especially for the junior folks.
In your experience, is there more substance use (drugs, assuming alcohol is used sometimes to excess by all age groups) among the junior folks, because of the difference in the pressure they feel?
That would require more speculation than I’m willing to engage in. I can comment on the various pressures to perform that apply to older and younger tech folks, and why I personally don’t feel the need to go the Adderall route (essentially I don’t think the results of merely more output are worth it). To put the two together I’d encourage you to find people currently going down that route for their perspective. Given the discussion here it shouldn’t be hard to find a few! Good luck.
