Somebody scoffed, "Oh, you'll never do that-- At least, no one ever has done it," But he took off his coat and he took off his hat, And the first thing we knew he'd begun it. With a bit of a grin and a lift of his chin Without any doubting or quit it He started to sing as he tackled the thing That couldn't be done--and he did it.

There are thousands to tell you it cannot be done, There are thousands to prophesy failure, There are thousands to point out, one by one, The dangers that wait to assail you; But just buckle in with a bit of a grin, Take off your coat and go to it; Just start in to sing as you tackle the thing That cannot be done--and you'll do it.

Sometimes it is of as great value to be able to forget as it is to be able to remember. You have seen that each time you review a mental impression it becomes stronger and more deeply implanted in the brain. When using your Hitching Post for temporary purposes refuse to see the pictures after having used them, and your Hitching Posts will be free for filling any other information.

The unfortunate or embarrassing situations of life which you wish to eliminate from your mind can be forgotten by the same process. Each time you allow this circumstance to enter your mind you see again the conditions which you are trying to forget. This is just the thing you should not do. Each time you rehearse the subject you drive it deeper and deeper into your mind.

To forget you must refuse to review or to revisualize. There must be an utter absence of this circumstance from your mind. This will require some determination upon your part, and a little application of WILL POWER, but it is not a difficult thing to accomplish. The best method of eliminating a troublesome thought is to fill your mind with a pleasant one. When there is a tendency to recall that which you wish to forget do not deny it, but rather begin immediately to think of something entirely different and keep your mind continuously upon the new thought and the old will be completely eliminated.
