The best advice would be to leave emotions out the door. There is no scenario where people could feel fear, happiness, joy, excitement, sadness and many other emotions and still be a great trader. I know you should feel amazingly happy when you turn 100 bucks into 10k right? That is a huge return and your hundred bucks is now ten thousand dollars so you should feel happy at the very least? Well that is wrong, you should not because your 10k could become 100 dollars as well if you invest it into some scam type project, which is why always be careful and always keep your emotions in check.

Same goes for losing money, just because you lost money a bit right now doesn't mean that you will end up losing money constantly, you may end up recovering that loss and making a great return as well. Just focus on what you can do and do not feel emotions and worry about what you can't change.
