You can say that but sometimes there is just no way to get it right without trying stuff that doesn't work, improving on that, and throwing the old stuff away.

You can say that but sometimes there is just no way to get it right without trying stuff that doesn't work, improving on that, and throwing the old stuff away. You can't plan ahead and take your time to do things the right way because you don't know what the right way is. Iterating quickly is a way to work through those approaches quickly, and throwing away bad approaches is better than refining the wrong one. John Carmack: Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better.
