Actually, you are said to be very lucky in your career. It says that your boss might promote you or increase your salary. For this reason, some other people are dissatisfied and jealous of you. Then your relationship with your colleagues doesn't go well. You need to pay much attention in your job and try to maintain your relationship with your clients and "contacts" well.

And I think you are a bit sensitive. You shouldn't care about other people too much. Instead, you should focus on your job and do your best to make success.
