Why is it so difficult?
In my case it was my big ego. Donning it I realize how big it was. Where is your ego esham, minus the zegna and ferragamo? Who are you and what is your worth minus the branded wrappings?
You are but one who was created fom a drop of the “nuftah”. At best you are but a drop of dew.
You realized how small you were. At any time you can just vaporize.
