Keep Yourself free from common Follies.

Keep Yourself free from common Follies. This is a special stroke of policy. They are of special power because they are general, so that many who would not be led away by any individual folly cannot escape the universal failing. Among these are to be counted the common prejudice that any one is satisfied with his fortune, however great, or unsatisfied with his intellect, however poor it is. Or again, that each, being discontented with his own lot, envies that of others; or further, that persons of to-day praise the things of yesterday, and those here the things there. Everything past seems best and everything distant is more valued. He is as great a fool that laughs at all as he that weeps at all.
