I need to start making money. I go to school. I want to make money and go on a vacation trip with the class. Should I start betting on sports?
Betting is not a full time earning source. You may won few bets and lose few also. I have seen many people who have lost all their money in gambling.
Since you're are student and go to school, you can take money from your parents for the vacation trip. If you are short on money, try to do odd jobs in your free time and earn money.
