Go for it!

I get paid well to do quality work by employers who appreciate the value of that. Why would I care about whether someone who is content with mediocrity finds that insufferable?

My message goes out to those who want to do quality work, who maybe aren't there quite yet, and are keeping their minds open: don't give up. Every little bit helps. Every career transition you make to a firm that has a little bit of a higher bar than the one before is a difference to be proud of, and one day, you eventually arrive at one that's fairly close to the top. Be patient, keep improving, and don't give up! You can do it!
