What would you do differently?
I myself, I wouldn’t have gone into engineering. Too much work, not enough benefit. Getting a basket weaving degree is much easier, faster payoff, cheaper.
You're right about lots of work, but I saw more than enough benefit to justify the decision. I worked on projects for spacecraft, industrial electronics, consumer electronics, the recording industry, government research, and software security. It's been a great ride, starting to draw to a close (I'm 70).
There've been some tough spots, for sure, but overall I wouldn't do much differently.
