I can totally relate to this, especially the hacked Magento build part and "you won't leave until it's done". Good lord, that was my life for so long.

I've had the opportunity to meet a lot of junior devs and I'm envious of their jobs. It was a lot wilder and messier when I started but I now see juniors in more developed, mature roles than me. I can't help but be envious.

The real trick is to not get burn out and lose your love for the industry.
