It is very important to be patient when you are trading on a tennis court. ‘TRADING?!’ I hear you cry. ‘It’s bad enough trying to win the point without having to negotiate the price of a barrel of crude oil at the same time’. Well actually ‘trading’ is the modern parlance for the phase in a point where neither player is on top. So don’t try and force the issue – be patient and wait for your opportunity to present itself.
