you ever wonder if your whole career was a mistake

you ever wonder if your whole career was a mistake
me at 34yo doing QA, and doing about 15$ per music album release
but honestly this is just hard bc capitalism is not made to help people that have an artistic sidegig strive
I have spent all summer bouncing back and forth on whether I should go get a PhD so: yes
Definitely not a mistake, but never too late to make a change informed by all your experience!
