I know this post is a bit old, but nope! I'm 24 and starting something new. I think being satisfied in your work is super important, so I love learning about people's careers. If this is still giving you anxiety, you should feel free to pm me and we can talk it out. There's usually quite a few resources people are unaware of to help them find a career they'll love.

I know people who have started a new career at 50!

If it's what you want it's never too old

Hell no! It's not too late and it's never too late.At 58, I'm looking for a new gig myself!
