Oh, the joy!
Query emails going out, rejections now starting to roll in. Most people would be depressed, upset, angry. WHY?
You have to get rejected to be accepted. When I sold BMWs and Volvos for a living, I learned about sales averages. At that time, you had to talk to about 100 people to sell 1 car. At the dealership I worked at, you were expected to sell at least 10-15 cars a month. Anything less and it was talk with the sales manager time.
Try sending out 1,000 to 1,500 queries a month. You can see why car salesmen spend so much time at the dealership. Now, if you had the same rate of return, you'd have 10-15 agents interested in your 'product' at the end of the month.
Throw in the fact that you're not selling a known product. Raise the return rate to about 200 to 1 or higher. Yep, tough to sell a book.
You can't give up.
Me, I'm just getting started.
