Seneca quote

“The condition of all men who are busy with other things is wretched, but most wretched is that of men who busy themselves energetically in pursuits that are not even their own, who sleep to suit another's sleeping pattern, who walk to suit another's pace, who feel love and hatred-the freest of all emotions-at another's bidding. If these men want to know how brief their life is, let them consider how small a part of it belongs to them.” –Seneca, Dialogues and Essays
