My motivation was that 2008 hurt very badly and it seemed like capitalism was falling apart and I remember someone started a thread about losing $1M+ in that year alone. So it was nice to start a thread about portfolios moving by that amount in the opposite direction. Back then the thought of that happening seemed very remote. People said the Dow would not rise to 10,000 again for years. I do think we are headed for a correction, but hopefully not that severe and the higher up we go hopefully the higher the bottom will be.
Plus there are threads on milestones and people talk about reaching a portfolio of $100k or $500k or $1M... Shouldn't we celebrate our successes, no matter what they are?
