To assist you in composing your personal biography – consider the following five paragraph format used by Australian author Emily Gower.
Introduction: who you are, titles, company name, what you do for people (summary)
Background: qualifications, experience, how you got to do what you do
Service: how you work (consults, speaking gigs, workshops, etc), the value you offer, unique point of difference
Personal: ‘why’ (in form of quote), “I believe everyone has a voice and a message and it is my dedication to bring it out”
Conclusion: anything additional e.g publications in magazines, additional speaking gigs, value you offer people
