The secret of Buddhism is to remove all ideas, all concepts, in order for the truth to have a chance to penetrate, to reveal itself.
We seem to be going through a period of nostalgia, and everyone seems to think yesterday was better than today. I don't think it was, and I would advise you not to wait ten years before admitting today was great. If you're hung up on nostalgia, pretend today is yesterday and just go out and have one hell of a time.
