Maybe there are those who trade as their main source of income. perhaps they even only earn income from trading. but maybe one of the family members has to help to meet the needs. meaning there are other people who also work in the family.
when a trader has to meet his needs every day, it means he is trading under pressure. and it requires extraordinary calm to make money every day. Maybe you don't have to trade every day, but you definitely have a target to achieve certain profits.
Their are definitely people that trade as their source of income and they are making a leaving out of it, and some of them still make money from mentoring people and that is one of the best things, because no body will teach or mentor you free, and having a mentor is actually very good so we need more so we can not rely on how own knowledge, and that is why mentorship is very important since is not everyone that can learn on their own so the won't have a choice than to go for mentorship. Their is a way you can jut channel your to learn so that if you are taking trading as a source of income, you have to give it your all so that you don go hungry, because the moment you are not making money then how do take care of your self but except you will plan your self and also reduce the way at which you are spending money then buy what ever you need when you have money, that way you will be relieved of expensive and you won't struggle.
