Never doing anything with my life and instead doing what I'm told and getting a job I don't like consequently. I've heard of people getting jobs their parents wanted them to get because they wanted to please their parents, and they regretted it. I don't want that to happen.
In a large sense I fear a lack of purpose, indentity, and accomplishment.
I fear becoming a pretensious asshat.
I fear becoming stupid and unhuman... unable to experience human things like emotion and triumph and everything. I fear monotone, the inability to fluctuate between experiences and ideas and feelings. Assurance can only come after a moment of doubt, success can only come after a moment of work, ect. I fear being unable to think and see things.
