I think every day we get that chance to start afresh - even every minute really. I completely agree that the small details are the important ones. Most big moments are made up of the smaller ones that came before and could not be done all at once anyways. I see people that are not even in their own minds, but instead are watching media or playing games. This post is a good reminder to look inside and grow from there.
What you say about concentration is so true. Many people unfortunately cannot do that now.
