Don't be imperious or brusque. Learn to story-tell. Know how to present on the subject - if they're having race conditions, be able to explain race conditions well, for example. Don't pursue argument beyond it being productive, especially not for its own sake.

Make sure you're not proposing your personal One True Way. Be trustworthy.

At some point, people have to experience failure for themselves. You did, probably. Remember how that feels.

Ask to help, but that's a learned skill as well. You can't yank the wrench away from them. Set it up to where you can come in when they're in trouble, but be humble and "in the spirit of service."

I think being self-deprecating helps. Give ideas away. Make any conflict between (the collective) you and the problem, not you and them.

If people are defensive, learn to defuse that or accept responsibility for that, even if it's not your doing. And if all else fails, excuse yourself politely.

Sadly, a lot of this is basically charming or selling people. It has Venn overlap with seduction behavior.
