Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, that is way great spiritual giants are produced.
Ideas may drift into other minds, but they do not drift my way.
I have to go and fetch them. I know no work manual or mental to equal the
appalling heart-breaking anguish of fetching an idea from nowhere.
