We talk all day here about tweaking Windows, making the UI prettier etc. But the PC isn't the only thing there is to customize. We've already seen that a number of our skinners here customize other "stuff" when not at their PC, but one thing many people think of in terms of customizing is their life.
Lifehacker is one of my favorite sites and I try and hit it up at least once a day. While they do have stories on great little utilities to make your PC time more productive, and they often talk of skinning, their focus is much broader. Their focus is on customizing your entire life, from PC to job, to your cooking habits and beyond. Every day they post stories on tips to get the most out of even the most obscure aspects of life.
As an example, here are a few of the odd stories & tips you can find on their homepage right now:
It's a great site that is always packed with useful tips and ideas. Definitely worth adding to your daily site rotation.
