Yourself
Be very honest. This saves times. Lies and inaccurate information waste time.
Who are you Mentally, Physically and Spiritually?
Forget the "Strength" and "Weakness" label. It is what it is.
Who are you?
The more you know - the better.
Ignorance is the real weakness. Self knowledge is strength.
"if you know yourself - then you will be known.."
Your environment
Humans exist on earth because of the environment.
Our closest planets do not have the right environment for any living creature.
The environment determines who you are.
Geography, Systems (eco and people-made) and living creatures (especially people).
"If you know yourself - then you will be known. And you will understand that you are children of the living farther"
"If you do not know yourself - then you dwell in Poverty and you are poverty"
Gospel of Thomas
