On the weekend I came across the social site 43 Things. It's not new, but for some reason I had never heard about it. The site mixes an online wish list with a social network buddy list to make a kind of social aspirational sharing website. Sounds obscure but haave a look at it - I think it looks really useful.
So the idea is you write down things you'd aspire to do in your life (the top ones on the site right now include "finding balance in my life", "buy a bespoke suit" and "meditate daily") then you get to see people who want to do the same things as you, and you can also see what things your current friends aspire to do. So you get loads of ideas about the big things you could think about doing one day. I'm crap at that, so I think I'll start using this site and see what trouble it gets me in to.
