Hm, I guess not.
I see how you can see it that way, but that's not what I mean.
The biggest parts of life are psychological battles within yourself. Emotions, beliefs, actions, regrets, ect. All the big events on your mind. They are the biggest thing on your mind for a reason, always!
For example, let's just say you're going to a concert and you're really hyped about it. You would think that was the biggest thing on your mind, but then you have last Saturday's break up on your mind. That break up will rule as much as you want to deny it. And that thought in your mind with a psychological battle. You will always have spiraling or spinning thoughts about that event in your mind.
