Later this year, at the age of 32, I plan to quit my full-time job as a software developer and don't intend to look for another one. By then, I expect my portfolio will be large enough to fund my essential expenses for at least the next 30 years, if not indefinitely, so that getting another 9-to-5 job becomes an option rather than a necessity.
Making an investment plan and sticking to it does work in the long run. And that's good to know as the market regains some of its volatility and makes headlines with daily price moves. You can ignore the most extreme pundits and sleep better if you have the self-discipline to keep investing for the long run.
