Johnny Ball, TV Presenter, Maths Whizz, and father of Zoe Ball, currently presenting on Strictly Come Dancing, has sound advice:

" Have confidence in yourself, that you can always do more than you are doing. Never, never allow your ambition to be trapped in one thing. If you have an ability, or think you have an ability, then use it so you can never look back and say "What a Waste!"

Such good advice.  So what will you do?
