I guess most here already said the things that you need to do OP if you really want to pursue trading. Learn how to be emotionless not only on trading, but on investing in general.
I always feel like making emotions out of the equation is the only way to go. We're humans, we can't help but feel emotions.
Better is to have mechanisms in place that prevent those emotions from taking control.
Better to keep discipline not as something that relies on you but that relies on system.
Example. Make sure someone else has access to your portfolio. Multisig wallets. Stop loss that you cannot change without second approval. Simple stuff like that makes you a great trader regardless of emotion.
