Finding time for 'fun' stuff?

These days, I seem to be on a constant work cycle that doesn't seem to allow me much time to do the 'fun' web stuff or the personal projects that I used to. Yes, I maintain a few personal websites (that could probably do with a lot more attention from me) and I read a heap of RSS feeds that (I hope) keep me up-to-date with web design and development happenings but otherwise it's client work all the way.

By 'fun' stuff, I mean starting personal websites, creating and exploring different website layouts, testing out code examples, reading books about new web design (CSS3) methods, etc. I'm pretty sure I used to be able to set aside time for this but I seem to have fallen out of the habit.

In a similar vein, I have loads of reading that I keep meaning to do – books and back issues of .net magazine that litter my coffee table – but I cannot seem to get motivated to read as much as I used to. Perhaps my concentration span is less than it was. Or I am too immersed in client work during the day to get excited about more web stuff in the evenings. Or I need a holiday. I don't know.

Whatever is happening, I think I need to do something about it. Take a break. Set aside time in the week. Something.

All other suggestions gratefully received!
