Set Take Profit: Start to change trend after not reaching take profit

Keep falling to the cost price, not selling, or even floating loss
At this moment, there will be a voice inside: I just floated a 100%+ profit and didn't sell
How can I sell now with floating loss?
Next steps: either add to the position or hold on stubbornly
Because originally it was a profit, but ended up losing, this result can be very painful
At this point, it's no longer trading
It's gambling
It's about winning
It's about not accepting failure
But the market doesn't raise giant babies
There aren't that many perfect trades bought when rising and sold when falling
