I retired a few years ago in my late 50s after a fairly successful career in high tech. I've been in investing for 20+ years. I'm a continuous student of investing. Always seeking to learn more. Always reading another investment book. I'm basically a value investor. I follow very specific metrics. I have developed my own investing checklist. I track a lot of stocks. Having a methodical system has made me a successful investor although I'm always seeking to become better.
