Cold calling / meeting is tough in the beginning if you are introverted like I once was, but in my case the motivation to pick up the phone was knowing I would be able to put food on the table and pay the rent.
My first business was started when I had an idea for a software program and talked to a college professor. He put me in contact with another professor who just happened to know of someone in need of a software like what I envisioned. I agreed to write the software just how the customer wanted and they agreed to test. After the software was done, I began marketing it commercially and have since sold it in 56 countries.
