Smile in the mirror. Do that every morning and you'll start to see a big difference in your life.

This is going to make a big difference,

I do believe that I deserve what I have. I don't think I'm entitled to it. That's a big difference.

I learned there's a big difference between juniors and the pros.

But there is a big difference in working for the West and working for a totalitarian state.

It's a big difference catching pucks.
