I don't like making calls, going to appointments, job interviews and things like that. But in terms of the effort it takes me to do it, I noticed the first is usually the hardest one. So now I just procrastinate on purpose any calls or appointments I need to make that I can defer with little negative consequences. Eventually something shows up that I know I shouldn't delay, like an appointment with the doctor, or the dentist, or something like that. I force myself to do it and take it as an opportunity to do everything I had piled up, since I know once I make the first call it'll be easier to do the others. It can cause me to have a very frantic week when it happens but after I can relax again.
