I like asking bartenders about new beers. I enjoy trying their recommendations and determining whether I agree with their assessments. If I don’t agree with them I don’t get mad. I get a different drink next time, a little better informed. I won’t waste time being miserable about a bad beer. It’s not worth it.
You have expertise. Share it. If you’re not offering the whole of your skill and experience please ask yourself, “Why not?” Are you not being paid enough? Is it a fear that you’ll be judged? Do you not care about the project? You get what you give. If you’re holding back it’s likely the people around you are following your lead.
Make recommendations. Do you want to be valued as a creative person or a tool to execute some else’s ideas? Not all of your suggestions will be followed but the more you offer the more you influence.
