When old people speak it is not because of the sweetness of words in our mouths; it is because we see something which you do not see.
Just because something doesn't do what you planned it to do doesn't mean it's useless.
One day I think it's the greatest idea ever that I'm working on. The next day I think it's the worst that I've ever worked on - and I swing between that a lot. Some days I'm very happy with what I'm doing, and the next day I am desperate - it's not working out!
