His clients line up on park benches, some of them also turning out for free meals provided on Wednesdays by a local church. One by one they take a seat in a folding lawn chair above a car battery Cymerys uses to power his clippers.

As he finished a trim on one customer recently, a loud squeal came from the battery. He gathered the mobile shop, connected the clippers to his car and picked up where he left off.

"It really is love. I love these guys," Cymerys said. He paused and turned to his client in the chair, "You know I love you, right?"

"That's what it's all about," Cymerys said.

Q: How do you do it? How do you manage your time, the requests and the demands it takes to be a giver?

A: I try to incorporate the things I've learned in my research into my own life. One of the biggest things is asking the question, "Am I capable of helping uniquely in this situation?" I will help with the ones where I can add value that other people can't, if I have a unique expertise or connection. I (also) try to ask other people to participate, who are in a better position to help.
