I used to think the same way (read: about 3 months ago).
But what I've found is that by improving myself, my relationships with everyone in general improves. Even my friends who have nothing in common with me - I feel more bonded to them now than I did before all this PD stuff. I guess it's through acceptance, and loving reality, I naturally see their positives. I used to get really cut if one of them was being pessimistic, but now I'm far more accepting. Most of it rolls off me like water off a ducks back, now, and I find myself throwing PD techniques without thinking (like asking them casually where they see themselves in 5 years, and whether they're in alignment with it). Before that, I used to be so caught up in myself, I never noticed the people around me, and never asked them about themselves. Now I feel like I know them more than ever.
HTH.
