I am sorry for missing that. Thank you for correcting.
About friend - I know why he is busy. He is not of the type that makes lame excuses. He will say it on my face if he does not want to do it.
I understand your point though and agree with your judgement. Reason I asked was that I can imagine myself doing the same for someone else. But maybe I am too naive.
You are asking someone to provide for you several hours of their time. Someone who is currently receiving $100 to $300 an hour at their company.
There are plenty of books. Get some, find other people who are trying to do the same as you, and practice together.
