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.
If you are financially stable or if you are not struggling about your finances anymore , you are just trading for an emotional satisfaction. As for me, I am trading for money. I am so eager to earn because I would want to secure my future as well as my family and that would give me a contentment and satisfaction.
