There is little use..

in attaching significance to what the other person thinks of you. Different people have different views and it is impossible to please all of them. Happiness is a state of mind and it comes from within (yes it can be influenced by external factors but that is not lasting). So there is no point mulling over what the other person thinks of you and trying to change it. The opinions keep changing anyways. And there is no right or wrong.

What is much more important is that you are proud of who you are. Now, that perception counts. And only you can change it. :)
