There’s a great meme going around about geeks and repetitive tasks. Because geeks will often get annoyed at the effort of doing something manually, they often decide to find a way to automate it – which usually involves a lot more effort than doing it the one time but “geeks win, eventually” because they save time in the long run.

For a developer, the possibility of embarking upon a "green field" project is both a blessing and a curse. The blessing of course is that before you you have a blank canvas and a chance to build the perfect solution. You have a chance to avoid all of the mistakes that you've made before.
