David,
Focus on the present.
Be sincere.
Trust Yourself.
Above are the words I wrote on a post-it note (do you have those sticky notes in the UK?) about one half hour ago!
I decided I should post it in my bathroom somewhere... I want to keep reminding myself of the positive.
I recently started a new job... another opportunity for change and adventure.
The support we get here is wonderful, isn't it?
