Mary Spillane has been the UK's leading image consultant for many years. But her books and work have always gone much futher than advising on appearance and personal grooming.
Branding Yourself is all about presenting yourself to get the results in business and everywhere else which you really want and I found it hugely helpful.
Its lay out is user-friendly. Lots of white space, big margins and clear type. Her flip style is seductive, and its packed with jokes which make her sometimes tough messages more palatable (and memorable)
Try: 'Any old jacket and trousers do not make a power suit, Pseudo suit, yes; power suit, no.' or
'If you brush you teeth unconscious of any methodology, it's time to invest in an electric toothbrush..... Bad breath makes for bad deals.'
Her advice ranges from the dangers of being misconstrued by kissing on greeting in a business situation to how to handle yourself in an interview situation to get the result you want.
It's well indexed, there's a helpful reading list and lots of practical examples.
Try it - it may prove invaluable.
