Programming is more like modelling clay rather than carving stone. You can, and you should, always slowly reshape your creation until you are satisfied with the result. If you are carving stone there is no way that you can change it without destroying everything and starting again. You may be faster just using a lot of time thinking before writing the code, but you will never see the real essence that is revealed only while you are continuously moulding your creation. To me it always happens that after days or weeks or even months that I don't look at some part of my code I find a better way of doing it. One way that would have never been apparent without the code being in that current form.
