But that's wrong, you are wrong. Think in this way, if it doesn't work and it cost time, be patient, cheers for steps instead of goal being achieved. Everything else is just as usual. And one part is malfunctioning. It's no big problem! There'll always be some big projects that requires long work. Be faced, you can't always skip that dirty part.
When you've made this clear, think back about this situation, not that bad, aha?
