When you have got other sources of income then you can trade for emotional satisfaction. But, I am trading for money, as I don't have other sources of income. At this young age, I need a lot of money to support my family. So, If I can some, It would be good for my family.
I can say that it is both because in my personal belief you cannot trade successfully if you will have an attitude to earn money, it is not a job. Trading is more than a heart process, then irregular routine just acting.
