I'm a 66-year-old investor focused on dividends in a Retirement Income Portfolio. I've been a member of BetterInvesting.org since 1982 (formerly the National Association of Investment Clubs). For many years as a volunteer I helped lead workshops to teach tools developed by NAIC to educate investors about how to do basic fundamental stock analysis. I continue to have a strong interest in investor education.Better Investing's "four principles" have been very helpful to me:1) invest regularly throughout your lifetime; 2) invest in growth companies; 3) reinvest earnings and profits; 4) diversify by industry and size. Bill Bengen's "4% Rule" inspired my goal to design a retirement portfolio of individual dividend growth stocks as a way to tap only dividend income from the portfolio as long as possible rather than selling assets. Some things I've gleaned from mentors and colleagues: - Peter Lynch's conviction that the average person, with some study and discipline, can make good decisions about stocks; - Louis Rukeyser's ability to ask probing questions about the market; - From The Intelligent Investor, Benjamin Graham's focus on value; - From Better Investing columns, Charles Allmon's skill in finding growth stocks that also had the virtues of value and income;- Brad Thomas' analysis real estate investment trusts; - Bob Wells' disciplined search for dividend growth; - From The Single Best Investment, Lowell Miller's focus on quality and safety; - David Van Knapp's ability to keep the big picture in mind when designing a portfolio; - David Fish's dedication to monitor consistent dividend growth; - Factoids' distillation and dissemination of mounds of data;- Chowder's determination to buy and hold quality businesses; - BDC Buzz's clarity about the risks business development companies; - Tom Konrad's commitment to alternative energy investments; - George Fisher's insights about utility opportunities; - The Seeking Alpha community--both veterans and young contributors.
