The only way one can sustain themselves on the road is with solitude.
Solitude, and natural re-charging is more important than money. Money is actually what drives us to insanity. It drives humans to do unthinkable things like - sacrifice the little bit of time we have here on this earth to slave for the almighty dollar. And, I am not excluding myself. I am guilty too.
Money is man made. It is the root of all evil.
Gods Creation though...
That is where we worship.
And - one day - we will gladly go back to the Earth.
