I had a position when I worked at West Music where I had a colleague who just had a really bad attitude. I'm someone who is very positive. I like making sure that everyone around me is having a good time, is happy, doing well, and this person just, no matter how the day was going, just had a really bad attitude. And so that was someone who was completely opposite of me. So the way I dealt with that was to continue to be positive, continue to try to make my co-workers have a great day, and focus on my tasks at hand. Try to not let them influence my day. Make sure that I could get my job done well and that I could continue on with my good day.
