I don't want to come across as ingrateful for SRP as a forum, but put yourself in my shoes. The responses here have not exactly demonstrated a willingness to share information on how to become adept at honing or even how to start, so much as suggesting that this is a skill that only a select constituency - one that is exclusive of yours truly - possesses.
I have, in other hobbies and occupations, been in a situation to let people know that there is no 'magic bullet' to fix their problem/address their request, but I usually follow this up with the necessary steps to achieve the knowledge I am being asked of.
I guess I expected the same, and I'd be lying if I told you I was anything but disappointed.
Surely, people who learn how to hone have a starting point, and that starting point cannot 100% of the time be asking another SRP member to mentor them.
