Hello. For context, I am in a university. I do not have any friends, and it feels like colleagues talk bad about me. This makes me quite hesitant to join any circles or attend seminars. I am not sure it is everyone who thinks bad about me though, I fear about asking. Yet I plan to do research, so I should attend seminars to learn current trends and stuffs. May I ask what I should do in such a situation? Are friends necessary, or not really? Also should I stop being in this environment and get a job instead? Thanks for reading lengthy paragraph, I would love any comments or advice for this.
Unless you are independently wealthy, you will need the support of other people in your life. This is not avoidable - you must learn to live and work with other humans, and hopefully also enjoy their company.
The good news is that social skills are a thing that you can learn like any other skill. There are books about it, but the trouble with that is (1) advice in the book is cultural context dependent, and therefore most applicable in the time and place where the book was written, and (2) reading a book is an inherently non-social activity, and therefore not really contributing to developing the skill.
The best way to learn social skills is through observation and practice - which means that you will have to put yourself in situations that feel uncomfortable, until you learn enough that you become comfortable. This is a lot like learning to ride a bike - you feel clumsy, unsteady and slow at first but if you keep doing it you learn to stay balanced, and eventually it feels natural. You have to push yourself past the point of discomfort.
