The idea of dialogue is overrated- sometimes you have to fight. There are certain issues we mustn't depoliticise, sometimes we must fight, and sometimes that fight is physical… that's just reality.

The pace was different – no hourly targets here – with a collegiate atmosphere that placed greater importance on future implications.

The strongest characteristic of art is that it belongs to the individual. Art is an expression of individualism and the opposite of oppressive dogma.

It's a matter of finding an approach that works for the individual. A person has to know whether they are comfortable with fundamental or technical, long term or short term, certain types of markets, wider risk or less risk… You can go through a whole checklist of things and find it's different for each individual.
