I was in the same situation as you in my 20s -- a small (but influential) subset of clients that paid the bills dictating what the company did. It limited the potential scope of anything we could do. Every project eventually fizzled out too. I'd get excited only to see the project canned months later.

I think you made the right call here. I wish you the best of luck in your new job! It's an exciting time. Happy belated birthday!
