I hark unto us all the point that we must never stop knowing ourselves. The loss of self, the loss of happiness, and the loss of the pursuit of happiness are the worst crimes in mankind.
You never want to be in the percentage of folks who live within a body and mind they don’t understand or deal very well with.
It is even worse when people or others (including yourself) appear happy or full in themselves, but deep down inside don’t have the self confidence and self trust to live life for themselves and the purpose they were created for in the first place.
Honestly the best advice to others and to ourselves is to: Know Thyself!
