Warren Buffet: "Selling your winners and holding your losers is like cutting the flowers and watering the weeds."
His biggest regrets are selling winners too early. We are HODL our SpaceX because we killed too many Golden Geese in the past. We didn't survive the 100 hour work weeks just to water weeds. Just trying to keep our cool and not be too tempted to sell pre-IPO for the bird-in-hand.
