What do you mean, don't talk about the past and the rest of your life?

If you don't talk about the past, you won't talk about everything in the past. If you don't talk about the rest of your life, you won't talk about the future. Generally speaking, you don't talk about the past, but live in the present wholeheartedly.

This attitude towards life should be relatively normal. No matter what happened before or what will happen in the future, it is best to live in the present.
