I think there is also some skill maturity also here. If someone can balance great interest in something with inner detachment, miracle can happens.
In my case, I get a trade go to 5% of my account, do I take it, what’s my target? Is it realistic, maybe I could get 7-8%, or even 20% for that trade… Let’s see where it’s going. Oh, definitly possible for it to go to 12%.
Or just reverse that, you take 4%, safe, reasonable profit, then you watch it go to 5%… Then 6, 7, 8, 15%… Before continuing and you realise you could have made 30%. How are my emotions?
And that’s in between all the times the strategy doesn’t work, all the time you lose following your playbook, all the time your greed makes you adjust your playbook a little tiny tiny bit… Maybe it ends up winning, or maybe it’s a loss, who knows? Or maybe the fear of losing, fear of losing money, being wrong! Makes you hesitate half a second before clicking and oops! Too late, if you enter the market now you get a bad deal…
Emotions just bend the perception of reality and at the moment, I need to stay detached of outcome, while striving to win (hence why Sanguine is not ideal because it also lowers my drive for it).
