A small body of determined spirits fired by an unquenchable faith in their mission can alter the course of history. -Mahatma Gandhi
Once you determine that it is what you are rather than what you have, you have given yourself an invisible armor and a secret source of energy. Now you are proof against the opinions of others, and this is the lifting of a mighty burden. No longer thinking of profit and loss, buying things and what others will think, you have a vast amount of reserve life to spend on developing character and survivability.
Let’s change that a little, “…a determined spirit, fired by an unquenchable faith in his mission..” There is no outside force that can give you that, or take it from you once you have developed it.
I don’t always fine art to exactly illustrate a quote, but in this case it is appropriate. The picture depicts the 47 samurai. You should read their story, see the various movies.
