Walk in the park

I was out for a walk in the park this morning and I was thinking is this trading game a walk in the park or what? As long as we apply the same thought process to each trade in each race and do the same everyday, would it lead to a pot of gold, or as I suspect do we have to overcome the thought of laying a horse @ 9's for £100 see a massive red figure above ( even if its only for few seconds) and then going to a back of nerves? Why would we do that its the same thought process be with an extra zero or two on the end.
