Cautiously avoid speaking of the domestic affairs either of yourself, or of other people. Yours are nothing to them but tedious gossip; and theirs are nothing to you.
Lord ChesterfieldYoung men are as apt to think themselves wise enough, as drunken men are to think themselves sober enough. They look upon spirit to be a much better thing than experience; which they call coldness. They are but half mistaken; for though spirit without experience is dangerous, experience without spirit is languid and ineffective.
Lord ChesterfieldRemember that whatever knowledge you do not solidly lay the foundation of before you are eighteen, you will never be master of while you breathe.
