I am in a unique position that does not involve consulting/billing rates any longer, so that helps. However I did say 'by' 55, so it could be sooner as long as chit doesn't hit the fan. 😆Me too, fellow PE but won’t make 55. That’s almost too long to not be in management. Seems the “doers” age out when their hourly rate goes too high compared to fresh grads.
I'm probably considered a Boglehead/F.I.R.E. hybrid, although not a staunch follower of either movement. Started using similar tactics long before I heard of either.
Oh, and I don't plan to quit working, just find something else to do that's easier on the cranium.
