These days when I'm away from my family for business, I feel really sad. I think of those missed days when my son goes to school, or when my wife cooks really good meals. Some days, I'm busy, but at night I think of them. I call them. It's a small sacrifice when you put this beside my Mom's. I think of people who have suffered way, way more than me and thought: I should be thankful I'm still here. I should be thankful I have these opportunities.
