Wait until, on a good day, the market gain is equal to one's annual contribution. Even though one may have lost the same amount the day before, and it is a false gain, nevermind! The awesome thing is to see a one day gain equal to an annual contribution or an annual income!! Wow.....does that ever give a guy or gal a kick in the rump roast to keep at it.
I once knew a mustachian who, in 2008-2009 in the crash, was selling anything he had to raise money. I told him he was sorry he was having a hard time making ends meet, that he was selling his worldly possessions. He pulled me aside and told me that he hadn't lost his job, that he was trying to get a good paying second job, and that the reason he was selling everything he could make any money from was that the stock market was on sale and it was time to buy, buy, BUY, B-U-Y!!
I went home and bought $5000 worth of shares myself!
