The innermost drive of these successful nay-sayers is probably a positive one, since productivity is surely a positive thing. Most of the men quoted here emphasize the "I-can-do-it" attitude, and I would be guiding you falsely if I said otherwise.
There is no question that you should get down to the business at hand, without all the ifs, ands and buts. Produce, no matter what your view of life is. If you prize your caustic wit, you would do well to express it with caution on the job. Your sour outlook may not stop you from being productive, but it could have an adverse effect on co-workers and subordinates-to say nothing of superiors. Although getting your boss's job is still possible, it will be more difficult.
So let us concede this one to the formula men. Develop the "can-do" frame of mind, and you will be surprised how much you really can do.
This "can-do" attitude applies to your application for new jobs as well as to tasks on your present job. If you approach interviews with the idea of testing the company's suitability for you rather than your suitability for the company, your confidence will be immeasurably improved.
One word of caution: although a positive attitude is recommended, make certain that your approach is realistic. Avoid living in a world so dreamlike that any setback will upset you.

Don't be a fault-finding grouch; when you feel like find ing fault with somebody or something stop for a moment and think; there is very apt to be something wrong within yourself.

Reynolds
The world has a way of giving what is demanded of it. If you are frightened and look for failure and poverty, you will get them, no matter how hard you may try to succeed.

Nowhere is this truer than in business life, where bravery and faith bring both material and spiritual rewards. - Preston Bradley
Where all think alike, no one thinks very much. - Walter Lippmann

My general theory is that sound management is merely sound thinking coupled with effective execution. The problems of all businesses are essentially the same. Yet there is some justification for the man who insists that his business is different. It is different. Therefore, while the principles of management are undoubtedly the same throughout business, the applications differ of necessity, and it is in the application of principles which anyone can understand that management proves itself good or bad. - Herman Nelson
You all have powers you never dreamed of. You can do things you never thought you could do. There are no limitations in what you can do except the limitations in your own mind as to what you cannot do. Don't think you cannot. Think you can. - Darwin P. Kingsley
