Internal Brand

Topic is pretty broad, but I'm curious how people manage feedback internally as it relates to managing their perception.

I've always been of the opinion that I'm intelligent enough to it problems inside and outside of my team, and as long as I'm coming with a well thought out solution and not being a dick, it should be a positive.

That said, at my last company, once my brand was established my frustration definitely got the best of me a couple times when I felt like nothing was changing.

Looking for similar experiences and any takes to diffuse before being seen as a "know-it-all" sales guy.
