We do not receive wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can make for us, which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world.
I learned that we can do anything, but we can't do everything. . . at least not at the same time. So think of your priorities not in terms of what activities you do, but when you do them. Timing is everything.
