It's an online teaching job and as I heard, some of your clients give a little amount of tip.  Yes, that is a small amount maybe if you're not in the third world, but if you are here in my country, that's a big help and you can buy 1 kilo of rice with that amount.  But ain't have a talent for teaching stuff, ain't fluent to speak in English but for those who have that passion for that will probably worth it for them to have an extra income(not your source of income).

@uneng, I think OP it's good if you will lock your thread if you're satisfied with the answers of the earlier post.
