Tell me what to avoid, what to seek, by what studies to strengthen my tottering mind, how I may rebuff the waves that strike me abeam and drive me from my course, by what means I may be able to cope with all my evils, and by what means I can be rid of the calamities that have plunged in upon me and those into which I myself have plunged. Teach me how to bear the burden of sorrow without a groan on my part, and how to bear prosperity without making others groan; also, how to avoid waiting for the ultimate and inevitable end, and to beat a retreat of my own free will, when it seems proper to me to do so.
