Last 2 days I bought for about some cheap coins and it went down for about 5% or something and I decided to sell. And now, I am at full regret that all of those coins are now up for about 20%. My lesson for that is to be patient since the market was down for some day and it will always go back up.
Experience is really our best teacher. Just learn from it and make yourself stronger the next time around. Yes, in business we really need to have a strong heart and mind, and most of all have faith. Just move on and try again.
