I have no problems going up to just about anyone and everyone and asking for work. No matter how large, or small a $ amount involved. However I have one client, who I do, do work for that I am intimidated by. I have done a bunch of stuff for him in the past that was small and got paid, however he basically paid me what we both thought was fair, and to be quite honest I made out alright. However I am interested in doing more work for this client and his friends than what I am currently doing. Each time I try to ask the guy for work I get really nervous and can't do it. What is a good way to get over this feeling of intimidation?
