text: Your retirement plan is certainly possible, but be careful with words like "I will". Life catches us all by surprise. A plan is simply that, a plan. Unless you are able to invest entirely in cash equivalents, or stay out of investments and still reach your goal you are still to some degree at the mercy of the market. Used to be 10% was the minimum return you could expect, then it was be happy with 7%, now its 5%.  Bottom line however, I applaud you for your goal and if the plan goes as you intend enjoy your early retirement.
