David is a Chartered Accountant and Chartered Tax Adviser who does not ‘believe in’ the professions nor accountancy nor tax nor indeed man-made rules of any kind. He thinks business success, crudely, depends on building ‘the machine’ that produces the cash and that the only accounting that matters in business is cash management. But the machine must be beautiful to all beholders to be truly successful. If David was political (which he is not) he might be a combination of Nikolai Bukharin and Disraeli. One of his ambitions is to go back into mathematics and solve one of the remaining ‘David Hilbert’ list of 23 – ideally the Riemann hypothesis. Beware though, he has other bigger ambitions.
