The single biggest thing that turned my life around from my very humble beginnings was reading - I read for hours and hours a day and become 'well read' without knowing it from the age of six/ seven, I read everything I could get my hands on and spent every week in the library choosing my week's books, and my knowledge base and education grew despite the rather dreadful school I attended. It grew into a love of current affairs as I got older, global politics and economics and understanding 'how things work' because I was never taken out very much - the inside of my brain, my imagination and my mind just expanded and my individuality and interests were not driven by others.
The second biggest influence was having paints, paper, pencils and time. I was able to refine my own art and become accomplished. I discovered art galleries as I grew older to find inspiration, enjoyed urban and gritty art during my teen years and later the classics. The theatre, opera in Rome, the enchanting ballets and visits to ancient capitals, countries and tribes came later.
In my view cultural capital for children starts with this:
1)Take the screens away
2) Make books a big part of your children's lives - a huge variety from the library
3) Provide paints, pencils, paper and take your children to the countryside, city and river side to find their own inspiration with a picnic and paints in all seasons
The rest will come in due course
