I didn't take it as snarky. I could write a long essay on how I've used the experiences of those older than me to make decisions, but I'll spare you the diatribe. One strategy, though, is to ask people about their experiences. Do you mind sharing what was rough about those years in your 40s?
I had strong convictions about the things I would be doing and achieving in my 40s. The responsibilities that I actually had in my life were in direct conflict with that though. Initially I tried to do it all and just felt like a failure on all fronts. It wasn't until I accepted that I had way less control in life than I imagined that I was able to let go of the things I thought I should be doing and instead embrace and enjoy the things I needed to be doing.
