I think it can be the both,some persons see it as a lifetime job,while some persons do not see it as such,but for those who see it as a lifetime job,they are the ones who go extra mile to knowing more things about trading.They lose more,get more experience and try new things about trading Because they believe they want to earn a living through it.While these other set of people who assume trading is not a lifetime job only feels it is right to trade at their convinient,and to trade when they have no pressure on them,and with a lesser amount.They believe trading is more risky that we can immagine.
