Recently, I was talking to one of my relatives who has a very irritating personality. This fact is known to everyone in the family, but the relative himself doesn't seem to get it. I wondering if I also have similar issues in my personality which I might not be able to identify my self but might be obvious to the other person. Is there any technique out there which helps to identify negative aspects in one's personality and ways to over come it ??
Any ideas are welcome. Thanks
Edit: It is tangentially related to personal productivity, as identifying these kind of personality issues can lead us to path of self improvement.
