These are two conflcting opinions about you, do people perceive you to be too nice or do they get intimidated?
There was a time a felt the way you did, though at that time, my response was, who cares, if someone doesn’t like me he can **** ***.
However, what helped me was comapny of couple of very old high school friends who are extremely good in their social skills and i learned a lot from them. If you can find one like that it can be very valuable. Let them critique you and change ur behavior. I found that it helped me a lot and met at ease with dealing with people and i could get my things done much more easily. However, one tends to drift off to old ways with passage of time and when i feel like that i go back to my old companions for a refereshment.
