You reach a point where you say "f*ck it" and just move on. If I cared what people thought of me, I would be miserable all the time. Why waste all your time and energy trying to fit in? It's pointless. If you don't fit in now, chances are you never will and YOU have to accept that. I never fit in, even when I was 5,6,7, on and on...I was always the weirdo. I simply found other weirdos to be around than try and change myself and fit in.
I know people look at me and think, "Wow, how can she have a job looking like that? (I'm very pierced and tattooed and work from home, actually). How can a guy LIKE someone like that? (happily married, thank you). What do her parents think?(my parents taught me to BE MYSELF, period and love me and are proud of me)."
So this is all I need and all I'll ever need. I don't need approval from others, only from myself.
