"Some persons can give themselves away to an ambitious pursuit and have that be all the giving-themselves-away-to-something they need to do. Though sometimes this changes as the players get older and the pursuit more stress-fraught. American experience seems to suggest that people are virtually unlimited in their need to give themselves away, on various levels. Some just prefer to do it in secret."

I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for.
