Habitual Negativity
Habitual negativity could stem from lack of meaning and direction in one’s life.

When you seek out things that are wrong, you are seeking things that are worthy of your immediate attention. With the human negativity bias, this is an easy quick fix to fill the void with but it’s not conducive to a life worth living. You’ll run out of energy sooner than the world runs out of problems. You'll wind up defeated.

“If I just fix this, it’ll all be fine, and I’ll be happy” is the subconscious attitude that drives me during my depressive episodes. In reality, I’m in a state that’s primed to spot things that aren’t quite right or make things that are fine seem like they aren’t.

This is a good moment to mention that emotions are not a reflection of reality. Emotions that permeate you in a way you are not fully conscious of tend to paint the world with colors befitting the emotion. The world is then distorted through twisted lenses of emotion and when this perception is allowed to go unexamined, it will in turn validate the feeling that helped to create the perception. It is a self-perpetuating cycle kept alive by the emotion.

It helps me to think that the world out there is okay. It's just that I'm not feeling okay. This cracks open a tiny gap in the insulated bubble of my mood and allows hope to shine in.

Gift of Anger
We are conditioned to view anger as something unsightly. It's a highly disruptive to social cohesion, and I believe a functional society requires its members to stifle their bursts of anger to keep everything running smoothly. No one can put their emotions and themselves on a pedestal. If everyone did that, the fragile synchrony keeping society together would be fractured. Without anger, we are good, undisruptive members of society... whose ability to value has been severely inhibited.

Anger signifies willingness and capacity to fight for something. It arises when something important to us is under threat, a red hot exclamation mark that we are willing to put ourselves on the line to preserve what we value.

An angerless human is pleasant and undisruptive, but he is also tragically deprived. He cannot hold anything too dear, because should it come down to it, he cannot hold onto it. Whatever he has, he has to live with the knowledge he could lose it all in a flash and there's barely anything he can do about it. He will have great difficulties telling others when they are mistreating him. He will have great difficulties to tell when others are mistreating him as there is very little inside to highlight the moment when boundaries are trespassed. He's forced to live life at the mercy of the whims of others or forever removed from rest of humanity and the ever-present threat of their autonomy.

Beliefs
Beliefs may seem kind of silly and childish. After all, we're rational adults, aren't we? We operate from a place of mature logic, not baseless beliefs... Except there's a bit more nuance to it. Sure, experience refines our mental models that guide us through life without getting ourselves hurt as much, but those mental models are, too, beliefs. Beliefs that err towards the side of caution, and thus rarely get tested. It's not a flaw, but a feature you can use to either expand or shrink your life. Try believing you can do that thing sometimes. You may find yourself tackling it with just enough confidence to propel yourself all the way to success.
