I am not really one for pushing books onto people, but here is a short list of some that I have found uplifting, useful and inspirational:

I have added easy links to Amazon below, so you can buy them immediately, I'd recommend every one of them, but here's a bit about each one:

• The 7 habits: the most inspirational book I have ever read: a real life changer: focusing on the principles of effectiveness.
• The 7 habits for teens: the version written in easy english by Stephen Covey's son, Sean ... almost better than the original!
• Man's search for meaning: the true story of Victor Frankl's time in Auschwitz, where he discivered 'Man's ultimate freedom'. This book is a cracker.
• Long walk to freedom: the autobiography of Nelson Mandela. It is clear from this why he's regarded as an icon of the 20th century.
• Raving Fans! : anyone involved in serving customers must read this. It's also short and fun!
• 1 minute manager: the original management book: makes it simple, but very effective. Again, it's short and fun.
• Good to great: explains why & how some Companies become and remain great, while most remain average or good at best.
• Just William: get these on CD, read by Martin Jarvis: a real treat for a long car journey for adults and children alike: I can't recommend these too highly!
• The heart of success: another 'milestone' book. Outlines what is really important, rather than simply urgent. Some fantastic gems of wisdom in here.
• The dangerous book for boys: the title says it all: delightfully un PC!
• Helping clients succeed: the book that will transform your success rate in selling and consulting: amazingly good.
• The 8th habit: another one from the Covey stable: as good as ever.

ENJOY! These people have spent lifetimes to bring us this fantastic material.
