The question is not how would you live. The question is how much of what you have do you wish to spend? I am going to spend all of my principal. Think of your principal as funding an annuity.
You can draw down the principal while collecting earnings and by doing the math you can smooth the flow to essentially equal payments. The math is the same basic math as a fixed mortgage payment except in reverse.
The next question is how and where to invest. If you want minimal risk and fluctuation then you will seek one type of investment if you do not mind a level of risk and therefore some possible fluctuations you may invest differently.
