Back in 1990, at a time when I was young, ambitious and living in London, I embarked upon a new start-up adventure with Gunther, a very successful German businessman. I initially met Gunther at an international congress and he took a shine to me because I challenged his views and offered a different perspective. Although he was of a similar age to me, little did I know that he was extremely wealthy. His humble understated demeanour gave no hint of his self-made success and resources.
