BWT Who Are Career Late Bloomers

Long story short - I’m a complete failure career wise. Been working in accounting the past five years and hate every second of it - zero growth due to a combination of bad luck and bad decisions. Have any other BWT gone through something similar, where they had a really rough start to their career and yet found success later on? How did you pull it off, whether it be through a new degree, networking, etc? Seeing so many of my peers who are accelerating so rapidly, which just makes me feel even worse about my situation. I keep oscillating between trying to stick it out a little while longer in the hopes that things get better or just going back to school to start from scratch in a completely new field (which seems a bit daunting given that I’d be starting anew at ~30).
