_Vacillation of mind_ is a common fault. Many small questions have to be settled and a few important ones. Some are in the habit of deferring their decisions from time to time, or making and revoking their decisions. Then they decide over again, after which there is another revocation. This is repeated until it is absolutely necessary to make a final decision. By this time the mind is so muddled that the chances are that the last decision will be inferior to the first one. No one who leads an active life can be right all the time. He who is right six times out of ten does pretty well, and he who can make a correct decision three times out of four can command a fine salary as an executive or build up a flourishing business of his own, if his mind is active. The doubt and uncertainty which result from unsettled questions, which should be promptly decided, are more harmful than an occasional error. The untroubled mind works most quickly and truly. Related to this in minor key is the doubtful condition of mind where the individual has to do things several times before he is sure they are properly done. For instance, there is the man who must try the office door several times to be sure that it is locked and after being satisfied on this point he is obliged to unlock it and investigate the condition of the safe door. Then it is necessary to attend to the office door two or three times again. This kind of doubtfulness takes many forms. It does no special harm except that it leads to much waste of time. Such people should teach themselves concentration, thinking about one thing only at a time, until they learn that when a thing is done it is properly done. _Judging_: Many insist on passing judgment on everything and everybody that come to their notice. Every individual has to be placed with the sheep or the goats. This is a great waste of time. Each one of us can know so little about the majority of individuals we meet and of the vast volume of knowledge that is to be had that if we try to judge everyone and everything, our opinions become worthless. Wise people are never afraid to say, "I don't know." If it is necessary to judge, let there be kindness. _Volunteering advice_: This is another annoying habit. It is very well to give advice if it is desired and asked for, otherwise it is a waste of time. Take a person with a cold, for example: If he meets twenty people he may be told of fifteen different cures for it, ranging from goose grease on a red rag to suggestive therapeutics. If he were to act upon all the advice received there would probably be a funeral. It is best to be sparing with advice. Those who have any that is worth while will be asked for it and paid for their trouble. Free advice is generally worth what it costs.
