There are few people who see an upside to the record-setting drought in California, but Drew McClellan sees a path to business. Earlier this summer, when a friend began complaining about his browning front lawn, Mr. McClellan thought back to his childhood in Florida, where he often spotted golf courses using sprays to dye their greens. When a brief Internet search failed to show any local business offering a similar service, Mr. McClellan decided it was a prime opportunity.

And since he opened up shop in July, Mr. McClellan has been taking requests faster than he can keep up.

Stories like this, they’re a mirror. They reflect back the mindset that you bring to it.
