I have cold called in the past. I would put in the people I communicate with and have a positive response from (please call again, send something in the mail, set appt). Everyone else gets left out. I don't know how important it is to track how many calls you make, you just need to know you are doing the work and the right kind of work.
Wind, I hate it and am terrible at it, but I did it for a while. I had a list I called on. What I did was set up an Excel spreadsheet that tracked when I made calls, with dates at the top. I would put an 'X' in the box when I called. This way I knew when to call back (for those I couldn't connect with).
Do you call on product or something else?
I've not done any cold calling to speak of. The little I did I hated and I sucked at it. Maybe I sucked at it because I hated it. There's no doubt that it works for some folks, but I have enough call reluctance as it is without dealing with cold calling.
I called out of the phonebook, I just put a circle in for a call and filled it in if I made contact. I would write down the date on the last call I made that day. This would probably work for whatever list you have.
Wind, I think you should keep doorknocking. It sounds like you were good at that. You can probably find as many people in an hour knocking on doors as you can dialing the phone.
Besides, you are 20-something -- why invest your time into a moribund form of prospecting. Very few people cold call these days. All the good prospects are on the Do Not Call list or screen their calls. Either stick with doorknocking or find a new way of connect with people.
