I was reading this today in the Book of Mormon, probably one of the best chapters in the book, if you ask me, Mosiah Chapter 2.
First, let me setup what's happening. This is a sermon done by a certain king named Benjamin who is facing death, but wants to give one last sermon before he dies:
10 I have not commanded you to come up hither that ye should fear me, or that ye should think that I of myself am more than a mortal man.
11 But I am like as yourselves, subject to all manner of infirmities in body and mind; yet I have been chosen by this people, and consecrated by my father, and was suffered by the hand of the Lord that I should be a ruler and a king over this people; and have been kept and preserved by his matchless power, to serve you with all the might, mind and strength which the Lord hath granted unto me.
14 And even I, myself, have labored with mine own hands that I might serve you, and that ye should not be laden with taxes, and that there should nothing come upon you which was grievous to be borne—and of all these things which I have spoken, ye yourselves are witnesses this day.
I think sometimes we expect too much out of our leaders, thinking they'll be our saviors or will be as powerful as supermen. I think also, when we're asked to lead, we shrink because we think to lead we have to be all-knowing and all-powerful.
This is not so and this is the message in this passage. To re-emphasize verse 11:
"But I am like as yourselves, subject to all manner of infirmities in body and mind;"
I can imagine the sicknesses, the days that he was just too tired or too scared to face the day. Or days where he was burdened by depression or stress or anxiety. He was human after all. So am I. So are you.
That doesn't give us an excuse not to lead. It doesn't give us an excuse to be to hard on those who lead us. Being a leader is not about being perfect, it's about serving those you lead "with all the might, mind and strength which the Lord hath granted unto [you]".
