Many deal with this by introspection and personal devices to stay on top. It's valuable to keep in mind that habitual self-delusion has a down side. Often we artists have such fragile egos that we neglect to associate ourselves with those others of the same profession who are truly great, but who may intimidate us. It's often through connections with role models and even offending persons that we are able to put our priorities together. These spheres of influence make for speed and can save a lot of trouble.
Great people know great people.
It's a matter of offering that person something that you can genuinely give of yourself. Sometimes it takes a little thought. And when you are able to do it successfully a couple of times it becomes easier and more natural. Even if a person does not like other people very much, one need not fear decency and human outreach. That is a sure way to lose sleep.
