The five pound value challenge

From www.robotii.co.uk:

This post is for those with some spare time on their hands, or those who want to make a difference in the world. The premise is very simple, just create and give away five pounds or equivalent of value.

This does not have to mean donating £5 to charity, it could be writing a blog post about your experience, giving some time to help someone out or anything that you feel generates value for someone.
