I rarely ever heard someone say not to look for perfection, but it's something that I completely agree with. I know this guy who bought like three Bitcoins at around $2000 and sold at around $17000. The vast majority of us here would be happy about that, but he's not just disappointed that he didn't sell at $20,000, but it almost seems as though he thinks he was dumb because of that.
Which leads me to another thing, which is knowing what's luck and skills. As a fucking noob he's thinking that if he would had sold at $20,000 it would show how smart he is, but he didn't and... It's all pure ignorance.
"All look people, I'm into Bitcoin for a week and made some money, look at how smart I am."
