I personally don’t care about being seen as rich – I don’t need the fancy house or cars. I just want to know that I can give up some or all work whenever I’d like to, and spend that time with my family without any financial pressure. I remember reading somewhere that “wealth is measured in time, not dollars” – and I believe that to be totally true. If I ever got a tattoo, that phrase would be highly considered to end up somewhere on my body.

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
