Why do you always have to adjust your mindset? When you lose, you stubbornly refuse to admit it; when you make a little profit, you rush to run away. This is essentially a gambler's mentality. If this continues, you won't be able to hold onto much when you win, and when you lose, you'll fall deeper and deeper into the pit, ultimately losing everything.
In the end, you can only change your mindset to change the predicament.
