Yes, that fact is very understandable, most young ones, they get carried away when they start earning, hence they spend without care. But personally i believe a person that actually sweat or went too a lot of stress and hustle to make money, would never spend it roughly no matter the age, because they understand what its like to find money. And also it is the duty of the parents or those incharge of them to always caution them when ever they make wrong choicesWell people that are saying it's not good for adolescent to start business or trading have their reasons for saying that maybe it is because once money start coming in their hands, there is tendency of them to be distracted. However business has no age.
