Tips from entrepreneur Jason Fried
(1) Understanding the buyer is the key to being a strong seller
Understanding what people really want to know—and how that differs from what you want to tell them—is a fundamental tenet of sales. And you can’t get good at making money unless you get good at selling.
(2) Sell only things you’d want to buy for yourself
(3) People are happy to pay for things that work well. Never be afraid to put a price on something. If you pour your heart into something and make it great, sell it. For real money. Even if there are free options, even if the market is flooded with free. People will pay for things they love.
(4) Don’t just charge. Try as many different pricing models as you can. That’s a great way to get better at making money.
