Having learned many things about cryptocurrency is a great advantage but it does not guarantee that you would be successful, ALWAYS. Being positive/optimistic is a plus. When you lose in a trade, in bounty camps, even in your personal life when you lose to your problems, you actually gain. You gain experience, you became more competent, wiser than ever before, so dont be afraid to lose. Just keep improving just as Michael Jordan said JUST DO IT.
I used to say a basic life rule... You can't always win, but, after saying it a lot of times i understand that we can't always lose, and that makes the difference. It applies to gambling, but applies too for trading or life in general.
And i'm agree, every time we lose is a good lesson, sometimes it hurts more than other ones, but makes us stronger. The important thing is not to fall... is to learn how to get back on your feet.
