"There is change in all things. You..." - Quote by Marcus Aurelius

“Forward, as occasion offers. Never look round to see whether any shall note it.... Be satisfied with success in even the smallest matter, and think that even such a result is no trifle.”

“Very little is needed to make a happy life; it is all within yourself, in your way of thinking.”

“A rational nature admits of nothing but what is serviceable to the rest of mankind.”

“If you blame others for something that happens in your life, then you must wait until they change in order to get better.”

“Don't swap horses in crossing a stream.”

“Personality is like a charioteer with two headstrong horses, each wanting to go in different directions.”

“We must see that consciousness is neither an isolated soul nor the mere function of a single nervous system, but of that totality of interrelated stars and galaxies which makes a nervous system possible.”

“Nature does nothing in vain, and in the use of means to her goals she is not prodigal.”

“Any particle in this universe can change in relation to any other particle; but take the whole universe as one.”
