A speaker can be enthusiastic without requiring everyone to share the same excitement immediately.

Enthusiasm is good to be near and easy to overplay. When it comes with an expectation of matching energy, listeners have to perform interest before they have had time to form it, and the ones who need to think first end up feeling like obstacles. Real agreement often arrives days later, quietly, and only if there was room for it.

Say what you find exciting and then leave a gap. Ask what people think rather than whether they are in, and treat a slow answer as consideration rather than a lack of interest.
