Plan for early retirement even if you don't want it. You may want to work forever, but the jobs may not want you. Already an issue for older ICs and I expect it will just get worse.
Certainly save money now and always especially if young like 20s. Stuff money away learn how to invest. Even if you're older save like your life depends on it right now. Even for emergency funds I'd suggest a year's worth not as cash but something just as easy to liquidate that won't lose much value.
Yes I'd say plan to retire as soon as you possibly can. Or switch gears to part-time work since younger workers will become increasingly annoying to you. You may like them but generational culture clash is natural.
