And of course important perspective can be obtained by referencing one of the greatest long-term investors of all time, Warren Buffett:
"If you expect to be a net saver during the next five years, should you hope for a higher or lower stock market during this period? Many investors get this one wrong. Even though they are going to be net buyers of stocks for many years to come, they are elated when stock prices rise and depressed when they fall. This reaction makes no sense. Only those who will be net sellers of equities in the near future should be happy at seeing stocks rise. Prospective purchasers should much prefer sinking prices."
Invest long-term and prosper, (wink to Star Trek).
