I think it would be healthy for you to wander out to a frontier and explore a boundary. You might even want to re-examine a taboo you haven't questioned in a while and tinker with a formula you thought you'd never change. I suspect that you would also learn a lot from gently pushing against a limit you've come to believe is permanent. Having said all that, I'm cautious about advising you to go further. If you get urges to actually transgress the boundary and break the taboo and smash through the limit, please do lots of due diligence. Know exactly what you're getting into and what the consequences might be.
