This is a great post by Damien Guard – “The Ten Commandments for Developers” although the post is directed mainly at client application developers the basic philosophy behind the post holds true for web dev too. Number 2 really strikes a chord
"Leave Startup Alone
Your app might be the centre of your world developing day and night – it’s not the centre of mine."
Damien’s also put together a lovely monospaced (fixed-width) font for programmers, Envy Code R, which can be downloaded here. As well as regular and bold variants the font includes a full italic version too and the obligatory italic-as-bold hack to get italic syntax highlighting in Visual Studio. There is also a registry hack (for Windows) that allows you to use the font at your command prompt.
