That they try their hardest. Period. End of answer.
I believe that, generally, those who are called as leaders are inspired more often than not, but I believe that's because they are sincere and try to seek inspiration. At the root, however, all I expect is their best effort - since that's all I can promise when I'm on the receiving end of the expectations.
After all, in the LDS Church, our leaders are us.
