It seems that everyone has become so accustomed to massive yearly gains in the stock market. If you're thinking about selling your investments after a minor drop in the market, then you really need to adjust your strategy. Maybe consider a money market fund or speaking to a financial advisor.

Everyone seems to have forgotten the risk that comes with investing. We have seen gains in the last few years that are unlikely to be repeated in the near future. There have been past periods where the market has been down over a significant number of years.

If you have time on your side and are diversified in index/mutual funds then you need to stay the course. If you have all of your money in a few individual tech stocks then you need to restrategize or stop complaining when you lose a significant amount of money.

If you are a new investor, it can be easy to get discouraged in these type of scenarios but as the market goes down, your future purchases will be at a lower price. Nothing is ever guaranteed and nothing goes up in a straight line.
