This type of questions often come from those affiliate who are unwilling to work. But I think, there's no need for pretence here. I just tell them that "THEIR ACTIVITY AND ACTIVENESS DETERMINES THE AMOUNT THEY COULD MAKE, AND THAT THERE ISN'T ANY LIMIT TO HOW MUCH THEY WOULD BE ABLE TO MAKE, BUT IT ALL DEPENDS ON THEM". And this simply means that "The ball is in their court".
