I usually just let it fade away gradually itself without finding other ways which can substantially eliminate it. Outside university I always feel lonely because I like the academic atmosphere which is not available outside university. I miss those peer interactions in university. I hope to go back to it soon. I have been mired in this academic desert floundering for eons. I can't meet anybody to talk about those academic disciplines I am interested in outside university at all.
I found education changes people greatly. I can feel people of different majors and professional fields have different dispositions. They talk differently and have different concepts of value. I feel incompatible with people whose fields are too far away from me.
