My reasons for owning more than...1..........more than 3
1. Its additicive

Just like joining so many ptr's etc
2. I work outside the home only 6 hours a week and have 2 small children, 1 is under 2 years old and I wanted to find something that would allow me to pay the bills and stay at home with her.
3. Doing this, I decide what hours I work......when my vacation is,,,,,,,,,how long my coffee break it......and can do the laundry inbetween
Thats why I have more than 4 or 5
