Here’s an interesting quote by Charles Haanel:

“Real power comes from within. All power that anybody can possibly use is within man, only waiting to be brought into visibility by his first recognizing it, and then affirming it as his, working it into his consciousness until he becomes one with it.

People say that they desire abundant life, and so they do, but so many interpret this to mean that if they will exercise their muscles or breathe scientifically, eat certain foods in certain ways, drink so many glasses of water every day of just a certain temperature, keep out of drafts, they will attain the abundant life they seek. The result of such methods is but indifferent. However, when man awakens to the truth, and affirms his oneness with all Life, he finds that he takes on the clear eye, the elastic step, the vigor of youth; he finds that he has discovered the source of all power.

All mistakes are but the mistakes of ignorance. Knowledge gaining and consequent power is what determines growth and evolution. The recognition and demonstration of knowledge is what constitutes power, and this power is spiritual power, and this spiritual power is the power which lies at the heart of all things; it is the soul of the universe.

If you have been faithful to your ideal, you will hear the call when circumstances are ready to materialize your plans and results will correspond in the exact ratio of your fidelity to your ideal. The ideal steadily held is what pre-determines and attracts the necessary conditions for its fulfillment.”
