Managing risk is key
Q: How do you convince someone to do something for you?
A: You manage the risk. In fact, you take as much risk away as possible.
Want to get booked at an A-list club? A club owner needs to sell lots of drinks. Can you lessen that risk?
Want to get more people to your shows? Think about all the things a person has to deal with when going to a show. Travel. Parking. Paying the cover. How can you make it easier for them?
Want more people to buy your CD? What are the risks involved? What has stopped you from buying a CD?
How do you keep your recording projects from going over budget?
What about press coverage? Radio? Podcasters?
Once you understand the risks you're asking someone to take for you, it's a lot easier to find ways to lift the pressure off them. And then it's a lot easier for them to say yes. Do this enough times, and it'll sure look a lot like luck.
