Heart with regrets

If you fill your heart with regrets of yesterday and the worries of tomorrow,

you have no today to be thankful for. 

Maybe I hope too much

"Maybe I hope too much. Maybe I dream too much. But at least I won't give up until I've tried, and I won't regret anything."

If you are not in the moment

"If you are not in the moment, you are either looking
 forward to uncertainty, or back to pain and regret."

I don't regret things I've done

"I don't regret things I've done. I regret the things I didn't
 do when I the a chance."
