If you sit in the forums of a large SaaS business ($100mm+ ARR) you'll find loads of problems (product ideas), each worth at least $5-10k MRR with a few having much larger potential. The same goes for subreddits.

I also really enjoy meeting with a diverse group of people with different jobs/roles in different industries. That's where the profitable niches are. Been missing those interactions since covid.

Another way to get outside your bubble is to escape your daily work/tasks, go exercise and let your mind wander. I like to pair this with a podcast. Loving @myfirstmilpod right now. Like a workout for the the idea part of your brain.
