I don't see any failure in the story you have put in the topic. Ok, let's say all of those stories are true, but wouldn't you have traded all of your Bitcoins voluntarily or under conscious circumstances?
I think it's natural that you did all that because at that time Bitcoin was not popular, so anyone would have done the same thing as you and Even Laszlo Hanyecz was willing to make a documented purchase of Pizza with 10,000 bitcoins.
Whatever happened in the past is part of the lesson for the future, now you can re-arrange past mistakes by trying to invest regularly in Bitcoin using the DCA method to accumulate assets periodically.
