Cloud eleven is a philosophy explaining a possible way to live. Its basic premise, as explained by Devin, is as follows:
"Get high off life, whatever your high may be, get high to the extreme."
Used in a positive manner, living on cloud eleven can allow one to progress to the top of their game and get maximum enjoyment out of life on planet Earth.
