In order not to succumb to that, Flynn says it’s important to know your motivation. “Passive income is important to me not just for the financial security but so I can spend time with my family,” he says. “I’ve been able to work from home and witness all my kids’ firsts. I have a one-year-old and a four-year-old, and that's what drives me and gets me pushing through those hard times and why I keep creating new products and why I want to help other people do the same thing.”

It's a little awkward, so we'll get straight to the point: This Thursday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36, and only ask you for one gift a year. But 98% of our readers in the U.S. are not responding to our messages, and time is running out to help in 2018. If everyone reading this gave $2.75, we could keep Wikipedia thriving for years to come. The price of your Thursday coffee is all we need. People warned us not to make Wikipedia a non-profit. But if Wikipedia were commercial, it would be a great loss. Wikipedia unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart of Wikipedia is a community of people working to bring you unlimited access to reliable information. Please take a minute to keep Wikipedia growing. Thank you.

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.
