It's never too late - never too late to start over, never too late to be happy.
When you can't remember why you're hurt, that's when you're healed. When you have to work real hard to re-create the pain, and you can't quite get there, that's when you're better.
You can do one of two things; just shut up, which is something I don't find easy, or learn an awful lot very fast, which is what I tried to do.
