Every time I see one of these imposter syndrome posts, I cannot relate.
Imposter Syndrome doesn't exist for me. Never has, never will.
It is a fallacy to think you have to be an expert to create things. It is a fallacy to compare yourself against others who may not spend as much time but get the details faster.
I don't focus on these details of life. I only care for the result and how to make things easier for myself next time I have to do something. If I don't get something, either try harder or leave it to another time. I've always accepted I will not have the best available information. I know I won't be paralyzed by that.
Imposter Syndrome is a psychological issue that is caused by environment. Maybe you are too malleable at your current stage. Inexperience is everywhere. Everyone is a noob at something. Build a filter. Education is not a competition. Shit is produced everyday and any noob can improve it. Naive solutions are not strictly always bad. Paralysis is.
The secret to overcoming your psychological manifestation? "Just fucking do it." Who cares if it (what you think or know) is not perfect.
