Here’s an interesting quote from Prentice Mulford:

“Force is the power which quickly lifts out of discouragement. Force is the power which, after a night of dejection and perhaps tears, takes you out in the morning, renews your hope and your confidence in yourself, gives you new plans, new ideas, and makes you see new opportunities.

Force is that quality or element which makes you stop brooding over mistakes or disappointments, and starts you again on the main track toward success. Force always turns your face toward ultimate success, and away from failure. You will find this element in every successful business man.

It is a spiritual power whether used by a good man or a bad one; whether used by a company of male or female gossips in tearing somebody’s character to pieces and sending them through the air a current of injurious thought or force, or by a company of friends whose talk has only for its aim the benefit of others.

You can have more and more of this quality by desiring it, or demanding it, when alone. But you can get far more of it by so desiring it in the company of such people as have a certain faith in the truth of the law, that the more minds who come together to call for force the more will each one receive through such co‑operation of demand.

Read the above sentence over again. It conveys a truth, so far as it is in the writer’s power to state it, which is of mighty import on the bread‑and‑butter, practical side of life.

Force is the element which drives away fear. It is the element which gives you tact and address. As you increase it, you can stand and assert yourself before those who in the past have browbeat you, bullied you, and overcome you by force of stronger will tyrannically exercised.

This is the power constantly used against those who are trying to get up in the world. No matter how good, how amiable, how well disposed you are toward others, if you lack force, if you lack the ability to assert yourself or get justice, if your wits are driven out of you temporarily by a snub, a frown, a sneer, you cannot succeed in the world; you cannot have that to which you are justly entitled.”
