It does not mean that we should be selfish and eager to take everything away from the other fellow.

On the contrary, it means that, with energy, we shall be successful _according to our brain tendency_.
Going back to our second chapter we find the phrase "taking stock" of ourselves.

Done rightly that alone will inspire success.

Now if we are a little farther along on the way towards sane living and the _ability to laugh_ and we know that after this struggle is over the battle is won we must use the powers that self-analysis gives us--_to fight_.

The mere recognition of them is power and we must not let them go to waste.
Energy is like steam--it cannot be generated under the boiling point.
