I consider myself a healthy person. I'm in my late forties and I exercise three or four times a week, between tennis and running.

Sometimes, I catch myself complaining about little things...

Last weekend, I was playing in a small tennis tournament, and between matches, the organizers asked for volunteers to be a "ball boy" during a wheelchair tennis match.

I wasn't ready for what I was about to feel. Seeing people much younger than me in a wheelchair was really hard. Watching the men — and a young woman — battling with their wheelchairs to reach the ball as fast as they could, and still managing to hit it over the net... it moved me deeply. I couldn’t hold back a few tears.

In that moment, I realized I have no reason to complain about my life. I should be grateful for it, every single day.

Have you ever experienced a moment like this? something that made you instantly feel more grateful for your life? I’d love to hear your story
