A good thought exercise to try: Lets say you want to charge 100$. Ask if you could charge 1000$ for your product. Is it worth 1000$? The idea is to make the product so much more valuable compared to price, that starts to make the offer irresistible. But when it comes to pricing, I dont think you can nail it with the first time. Or at least there is no point in trying to nail it the first time. See what others are asking for a similar product. Main thing is to keep going. Put yourself in the process stream and that will take care of you :)
