Definitely the major source of money comes from my daily job and it is not a lot of money but I really glad that early understood that investments it is absolutely important. When I was talking with my friends or colleagues I realize that a small amount of them invest money in assets. Especially they don't think about financial independence and often buy unnecessary things.
Obviously it is a waste when we only spend money on something or goods that are not needed, but when we can think for the long term or for the future then indeed, investment is the main thing to spend your money. So in this case I don't think money from anywhere will be a problem as long as you get the money in a good way to invest, because the thing to worry about is when someone invests from dirty money.
