Strength in numbers

It's all too easy to think that we can't make enough of a difference working alone on big challenges, or subdued by the feeling that there's no-one else out there doing the same.

Which makes it useful every now and again to hook up with organisations such as Avaaz and recognise that you're part of a team of 6,500,000 people committed to making a difference.

Here are some warm, fuzzy messages from folk who know that the effort is worthwhile.

Enjoy!
