Kevin DeYoung offers ten things he has learned:

1. Beware of preaching all your battles from seminary.
2. Be careful with offhanded comments.
3. Be yourself.
4. Remember there are different kinds of people listening.
5. Don’t let personal conflict creep into your message.
6. Make sure your best stuff is from the text.
7. Be a pastor for the whole church, not just part of it.
8. Don’t give them the whole elephant.
9. Root for others and don’t compare.
10. Tell your congregation you love them and are glad to be their pastor.

Here is his talk on this at Gordon-Conwell Theological Seminary, though he doesn’t follow all the order of the above.
