Chances come and go. Decisions are made in an instant. Is there a 2nd chance for many things?

Noting a line from Robert Frost's "The Road Not Taken" (which at the moment is stuck crudely with masking tape on my wall):

"Yet knowing how way leads on to way..."

I suppose its all about choices.
One choice leads to another.
Chances when not taken, are lost.
2nd chances? Not often do we get them..
