Letters 2.1

Judging by what you write me, and by what I hear, I am forming a good opinion regarding your future. You do not run hither and thither and distract yourself by changing your abode; for such restlessness is the sign of a disordered spirit. The primary indication, to my thinking, of a well-ordered mind is a man’s ability to remain in one place and linger in his own company.
