Letters 22.3

You must be not only present in the body, but watchful in mind, if you would avail yourself of the fleeting opportunity. Accordingly, look about you for the opportunity; if you see it, grasp it, and with all your energy and with all your strength devote yourself to this task,—to rid yourself of those business duties.

Now listen carefully to the opinion which I shall offer; it is my opinion that you should withdraw either from that kind of existence, or else from existence altogether. But I likewise maintain that you should take a gentle path, that you may loosen rather than cut the knot which you have bungled so badly in tying,—provided that if there shall be no other way of loosening it, you may actually cut it. No man is so faint-hearted that he would rather hang in suspense for ever than drop once for all.
