After joining a research group, I discovered my colleagues are always low-motivated. They play card games, computer online games and listen to songs with the loudspeakers on all the time. They never discuss research-related things, and the only time they open a spreadsheet is to calculate some kinds of points in online games. These all happen in office hours in the laboratory.
I expect my colleagues are happy to discuss with me about research problems, but it turns out nobody is willing to do this except my supervisor and some of the post-docs. They just focus on their entertainments. I do not know why they want to do a PhD, maybe they just want to delay the time joining the job market. However I really want to be trained as a good researcher and I am serious about my PhD. I cannot stay motivated all the time because their attitudes seems gradually affecting me, and the atmosphere is simply full of laziness. I can notice myself sometimes lowering my standard in research work now.
My supervisor seems ok with it and does not get angry at their slow and boring progress. My research interest matches quite well with my supervisor, and I do not want to change my supervisor just because of those low-motivated students. How can I still be motivated in a low-motivated environment?
