Humility is a great start!

Humor, also. Amuse others with your wit. Don't be insulting, it's not necessary

Be willing to have your opinion discounted for a while (see, humility). When you turn out to have been right often enough they will come around. If it doesn't work out that way, hmmm, maybe you lacked some necessary knowledge.

Actual knowledge can often trump an ability to figure it out quickly. Pay attention to people with experience in a new situation, even if their CPU clock is running slower than yours. Respect their database.
