When I was 18 and single I was a labor worker for a concrete company, making a measly $300 a week. Now, 13 years, and 7 kids later, I earn that much every single day! Im far from being rich, but it is a pretty descent living. Most would consider it a killer living, but lets be honest, KIDS EAT ALOT! Just take a look..... My Monthly Budget: Food $ 900 Rent $ 900 Electric $ 200 Water $ 50 Cable $ 100 Phone $ 50 Car $ 450 Insurance $ 100 Clothing $ 700 Diapers x3 $ 60 Formula x2 $ 400 Dr. Pepper $ 150 Cigaretts $ 300 Daily Needs $3000 Total $7360 Per Month (And I still have money in my pocket at the end of every day) To make a long story short, If I knew then what I know now, I probally would be rich by now. So if you are young, single and have no kids, or maybe just 1 kid. It really is possible for you to retire by 40 or even 30 if you work real hard. I make $300 every single day, and so can you.
