The world is a country which nobody ever yet knew by description; one must travel through it one’s self to be acquainted with it. - Philip Dormer Stanhope

Conceal your learning from the company.

Never display your learning, but on particular occasions. Reserve it for learned men, and let even these rather extort it from you, than appear forward to display it. Hence you will be deemed modest, and reputed to possess more knowledge than you really have. Never seem wiser or more learned than your company. The man who affects to display his learning, will be frequently questioned; and if found superficial, will be ridiculed and despised; if otherwise, he will be deemed a pedant. Nothing can lessen real merit (which will always shew itself) in the opinion of the world, but an ostentatious display by its possessor.

In seeking wisdom thou art wise; in imagining that thou hast attained it - thou art a fool.

In the currency of life, time is the most valuable coin.
