One of my 'things' that I struggle with quite a lot is that I'm not making a difference enough to this world - I go through phases of being quite upset by the thought that if I died today, the world would carry on without every knowing I was here.
In 12 days time, in a pub in Winchester there will be a gig going on.  It's a gig I've organised to raise money for Naomi House hospice for children and teenagers.  It's set to raise around £400 on my estimation, and on top of that, should be a night of great music too.
So I feel like I'm getting somewhere on that quest to fulfil my need to make a difference to the world (to justify being here...).  I've got a long way to go, but it's a start.
