I've seen this being posted around and it's spot on. No matter how much money you may lose by not selling at the peak, if you hold you will make solid progress because after the coming bubble the floor will be higher than the previous floor. So after a couple of years you will end up with a lot more money than trying to guess the right price to get out which is impossible and a big gamble not worth lossing your long term position over.
