I am very grateful when I meet others who know more than me.  I have 2 recordings on my phone of the local mech./friend explaining how the electrical system of the car starting system and understanding the purpose of the voltage regulator on my 1966 car.  The same with people who know how to prepare and paint cars. 

I am reading a book The Life Changing Art of Self -Brain Surgery to help change my life.  Man can he make his sentences so clear on what he writes about.  I am trying to change my gene structure to change my mental thinking to be able to make better choices, relations better, reduce stress, improve my memory, just better management of my life to make me easier to live with and be able to bless others.   So, I respectfully disagree with you statement.  :)

I highly admire people who know more than me and can do the things I can not do.  

What aggravates me is people who do not care about there business or who do not want to learn how to do it better.  I believe when a person opens a business he is not in the business to sell something.  He is in the business of service.  I always believed that anybody can hang out a shingle, but it takes caring and work to make the business work.
