Seneca Quotes, “Letters From A Stoic: Letter II”:
“You do not tear from place to place and unsettle yourself with one move after another. Restlessness of that sort is symptomatic of a sick mind. Nothing to my way of thinking, is better proof of a well ordered mind that a man’s ability to stop just where he is and pass the time in his own company. To be everywhere is to be nowhere.”

“Food that is vomited up as soon as it is eaten is not assimilated into the body and does not do one any good. Nothing hinders a cure so much as frequent changes of treatment.Nothing is so useful that it can be of any service in mere passing.” -Seneca,

Seneca Quote “Letters From A Stoic: Letter III”:
“People who never relax and people who are invariably in a relaxed state merit your disapproval — the former as much as the latter.

And the state of mind that looks on all activity as tiresome is not true repose, but a spineless inertia.”
