Working in support roles for 12 years how do you keep from burning out and actually grow

I have been working in tech support and escalation and dev support roles for over a decade now basically living in ticket queues. At this point it feels like a never ending treadmill. Find knowledge send response close ticket repeat. I have done this across multiple companies and I am starting to feel like I am wasting my time and not setting myself up for the future.

For those who have been in support long term how do you stop from going crazy with the monotony. Do you pursue certs lab work courses side projects or something else to keep growing. I need some strategy to feel like I am moving forward instead of just grinding through tickets every day.

Any advice or perspective would mean a lot.

TLDR: 12 years in support roles ticket grind feels like a treadmill. How do you keep your sanity and grow your skills while stuck in day to day support
