I started working when I was 11 going on 12. Making about 50 cents an hour when I first began but hey, I'm old, that was a long time ago and you have to start somewhere.
Babysit, animal sit, mow lawns, do errands, whatever it takes. Be creative and believe in yourself.
It can add up pretty quickly if you are good about saving and I love Don's idea about learning about how to invest in Real Estate.
The fact that you are reaching out to ask for help about how to help yourself says a lot about you (all good!).
If the mood strikes you, let us know how things are going.
