Not really - I don't interact with people in uni, I treat them as bugs wandering around. What I did, was to focus purely upon myself, studying, finding a job and focusing myself on being better in a field, I earn now decent money, whenever I have to pass some exams I do it with ease. They don't bother me or rather watch me with amaze - they know I have nothing to lose and I can make their lifes miserable within minutes.

Example from last semester - there was a project to write an app with documentation for our entire year and they don't even know how to code properly and would fail miserably. I did it within a day (learning myself doing that) and then I was allowed by professor to assign points for everyone, because I aggressively said, that if MY work will enable everyone to get the best grade, then I refuse to present it. I was allowed to do that, everyone got the lowest grade just to pass subject, I got the highest. They cannot even cope with getting a scholarship around me as I control everything.

Being selfish works only if you are seriously above others and can harm them. How can they harm me? I don't make social mistakes because I don't interact, I do my work and I could even fail them, but that would put some extra effort on me, which I don't have time for.
