I really don't think the issue is whehter or not one should "try" to "innovate" nearly as much as it it is whether or not one should listen to one's gut when said gut says to go a different way, even if it says it in a faint whisper. There's a lot of external pressure (and sometimes even more internal pressure) to ignore that voice of the gut, and it takes a lot of courage to not only listen, but to follow through on that call.
Now, if one's gut never makes that call, ok. But I think it's a rare human who goes through life without hearing it at least once or twice. The gut probably makes that call a helluva lot more times than that, but conditioning prevents a lot of people from hearing it. The ones who do hear it and do act on it are by no means guaranteed success. But oh well.
