hello  I'm a young man trying to learn the concepts of real estate investing to experience new things and perhaps pursue a career or part time as a stream of income

There is no reason to race through life and money is really not that important if you already are happy with what you have.Why do I give this advise as a investor.......because it is not for everyone and most beginners have no concept of the commitments required...most in fact never start.

I am self taught but very open minded to all ideas and concept's.
