I am an introvert and can't proactively stay in touch with other people. I respond very well to people who talk to me but don't initiate any conversation with others unless it is absolutely required.

Now here is a shocker. I am a sales guy and I am supposed to bring in new business! I am good at reaching out to people when I am wearing my sales hat and win their trust to get a deal. However, once I am back home, I go back into my shell.

I was upset with myself for a long time for my inability to interact with people in my private life. However, off late, have embraced my dual personality. I am now just happy being who I am and not worried about the fact that I don't have friends or people to hang out with. I also put my personal time to good use by reading a lot.

Long story short, you may want to consider embracing who you are.
