Apologies for the rather poor photograph, this book has been one of my favourites for a really long time now. It's so small that it takes around half an hour to actually sit and read, which is a perfect amount of time to take out of your day to relax.
It has lots of little inspirational hints and tips to help your confidence to grow and combat your fears.
Being an anxiety sufferer, this book has really motivated me in times where I did not have the confidence to fight my fears.
This page specifically is one of my favourites!
Definitely check it out for yourself if you're interested :)
