“Closely connected with our ideals, we find our visions and dreams. The man without a vision will never be anything but an ordinary man, and the people who never dream of greater things, will never get beyond ordinary things. It is our visions and dreams that lift our minds to lofty realms, that make us feel that there is something greater and better to work for; and when we become inspired with a desire to work for greater and better things, we will not only proceed to carry out those desires, but will finally secure suffrcient power to fulfil those desires. ‘The nation that has no vision shall perish.’ This is a great truth that we have heard a thousand times, and we know the reason why; but the same truth is applicable to man. If he has no vision, he will go down; but if he has visions, the highest and most perfect visions he can possibly imagine, and lives constantly for their realization, he will positively ascend in the scale. He will become a greater and a greater man, and those things that were at one time simply dreams, will, in the course of time, become actual realities.” ~~Christian D. Larson, Your Forces and How to Use Them

Here are some other more succinct quotes on the same subject:

“Intelligence without ambition is a bird without wings.” ~~ C. Archie Danielson

“Ambition is a dream with a V8 engine.” ~~Elvis Presley

“Dreams are not aspirations and ambitions. Aspirations and ambitions are strong desires to achieve something.”

-Brent Filson
