Please, please, please don't pull your money out (unless your investing in something ridiculous). I care enough about your financial well-being to make my first post. If anything, a market decline is a great time to double down and get more value for your investment dollar.
For a, hopefully, reassuring read, check out the stock market series at
jlcollinsnh.com/stock-series/. I'm not some big shot investor. In fact, I just started at the market high point last year, so I can empathize with your feelings of watching value drop on paper.
Good luck to you and your future market returns. And thank you everyone here for all the tips I've started to learn for mTurk... or is it mtruck?
