I must admit to being a 'centre stage' person. I wasn't always like that. As a young man, and up to about the age of thirty-five I'd have been a person who preferred to be behind the scenes. I guess I swung from being introverted to what I consider to be a much healthier balance, one who is quite happy to be alone and doing one's own thing, and also being centre stage.
My natural tendency towards creative writing enhanced the 'behind the scenes' person, whilst my introduction to public speaking (via Toastmasters, Evening Colleges, Rostrum et cetera) created in me a confidence which grew until I loved to be in the 'lime light.'
Today, I love standing centre stage addressing a big audience. Yet, I still feel comfortable being alone with myself as company.
