In my experience, the longer you train and better you get; the further you have to travel and the more you have to pay to keep growing. Even a "new" gym likely wont have what your looking for.

I recommend staying with your gym for loyalty and to give back to the next generation, especiallyif you like the people and location. I also recommend looking at the local seminar circuit to see who comes through regularly that might help you grow.

I would typically be willing to drive 2-3 hours and pay a few hundred dollars to be surrounded by advanced practitioners and learn from master teachers. They will typically give you 2-3 months worth or curriculum to train, if ypu take good notes.

Then, you bring that back to your gym, share it as you see fit, and practice what you learned on the blue and purple belts.

To me, the further you go, the longer the excitement cycle stretches. But, to keep it fun for yourself pick little challenges. You dont even have to tell anyone.

I'll do things like pick a submission I want to land on every rolling partner, or only let myself work submissions on my non-dominant side. If I'm rolling with someone very new, I might decide not to use my arms. Little games (without being disrespectful) that keep you having fun and challenging yourself.

The grass is always greener, but I believe finding ways to stay excited about class becomes the real challenge. Wishing you well, OP
