In addition to what everyone else is saying (i.e the IDEAL acronym), I'm looking to retire early and REI seems like the best vehicle. Everyone has different goals about financial independence, retirement, and supplemental income. I'm looking to create $3000-4000k/mon in CF within the next 3-4 years. I have a degree in chemical engineering and work "passively" in REI.
After working for 10 years in the corporate world, I learned the difference between a wage-slave and real wealth and have devoted my efforts to financial independence. It's shocking that a majority of folks are wage-slaves. A high paying W-2 really doesn't mean that much in terms of real wealth. I read Jacob Lund Fisker's works on this topic and this shifted my perspective on money, lifestyle, and financial choices. Next Rich Dad was the final nail in the coffin. I'm now committed to minimizing my consumption and maximizing my savings to achieve independence. Streamlining finances is a passion of mine.
Back to REI, I've found this is my vehicle of choice. I'm not interested in building an empire or being a millionaire. I've trained myself so that if I were to have a significant increase in cash flow and net worth, I don't think there's much that would change in my life as far as spending habits. Funny, now that I have a good understanding and a financial education, I don't care to spend money.
Here's to your wealth!
