It doesn’t matter how you choose to record your life story: Pen and paper, word processor, digital audio recorder or even video. The information can be played about with later – the important thing is to get it down in the first place.
People love you for you – so just relax and write the way you speak. Your character will shine through and be preserved for posterity.
Imagine your grandmother had left a record of her life and ask yourself what you would want to know. The answer is ‘everything’ – so do likewise.
No detail is too small – the fact that you remember an incident from more than 50 or 60 years ago must mean something. Get it down – you can always cut it later, if necessary.
Use anecdotes to illustrate the characters of people in your story, and include some of the social changes you’ve witnessed.
