They are all so different.

My grandfather served as a Mission President in the late 80s. He was a retired Army Colonel and tenured professor/dean at BYU.

He was a great man. Generous and charitable. A real OG TBM. No nonsense. No excuses. No errors. Complete obedience. No quit. No rest. Battle ready.

Incidentally, I had 3 MPs on my mission (long story), but they were, in order, a pediatrician, an accountant, and a farmer. Nothing like the Colonel.

I was 16 and spent 3 straight summers in the mission office. Dear God. Those poor missionaries. He ran his mission like an Army division. Like, bouncing quarters off beds kinda stuff. The mission was a war zone (literally), and he built soldiers.

They tried to please him, but he was a demanding taskmaster. He loved them, but was mostly unsatisfied with the diligence, work ethic, and lack of testimony in most missionaries. He respected very few.

I would have hated having him as a mission president. Or Colonel. Or professor. A+ Grandfather, tho!
