The saying is very true to me that you will only learn from your own experience and not from the others advice.
No the saying I like about experience is that " a wise man learns from another man's experience. In your own, you already talking like someone that knows that the action that you wanted to take to buy high is a wrong one or that something can go wrong but you went ahead to do that instead of waiting for another time. You wanted to pick a profit by forcing the market. So forcing the market is dangerous. I learnt this and I hope you did too.
