My hot take...
There is freaking no reason to keep working a $100K or more 9-5 job after age 35.
You've shown you have the skills and experience already. Every minute you stay is another minute you get underpaid. And if layoffs strike you're cooked.
I retired from corporate at 34. I'm not that smart.
The modern $100K+ 9-5 job is nothing more than cowards refusing to take a chance on themselves.
