Many young people would like to make a booth (货摊) in the name of entrepreneurship (创业精神) and sell lemon. It might seem like an easy sell—kids offering cool drinks. Some entrepreneurs offer their tips on how to make money from this.

Joe Mansueto, founder of the investment company Morningstar, sold lemonade as a kid. “You should always pay attention to customers,” he said. “When somebody’s walking down the street, get out from behind the booth, greet them, talk to them and just make friends with them to attract more customers.”

However, his two sons decided to sell a different drink. When they were 8 and 10, his boys sold cocoa outside their home. “The great thing about business is that there are really no rules. You can be creative and try something different,” Mansueto said.

But it wasn’t enough for US representative Mike Quigley and his older brother to sell drinks. They sold old books at the booth and would rent them out for customers to read while they enjoyed their drinks.

Adam Ochstein, founder of StratEx Partners, a human resources service company, gave frequent visitors cards which were printed with a lemon. Every five drinks, customers got one card which allowed them to pay less than half of the next drink. However, they didn’t price the drinks. “If you want to give nothing, give nothing. If you want to give $2, give $2. I think we had let the adults give more money than they probably would like to, “Today, he suggests kids use social media for marketing.” He said, “It can tell people where the booth is going to be and what unique specials you’re running.”
