I don’t know who Grant Cardone is but I like his investment philosophy. It makes sense to me.

  1. Invest in assets, not lifestyle. Don’t try to improve the quality of your life — your cars, where you live, your shoes, your belts, your purses or your vacations. Invest money in assets that create cash flow.
  2. Only use the cash flow from those investments to improve the quality of your life
  3. Continue that until your passive income is equal to your earned income

Seems simple enough. Buy assets that generate an income not liabilities.
