I'M REALLY CONFUSED😕

When i spend hours analyzing before taking a trade, everytime i end of losing money.
But when i don't feel like trading and I'm just tired, I only do 10 minutes of analysis and take a trade and somehow i always make a profit using the same strategy.

I really don't understand what's going on. I"m tired 😭

Should I change my Strategy??????

Even i made a profit on this trade yesterday, I'm still not happy. I just just feel confused inside.
