You are who you are. Never doubt that. You only have one single life so put everything in it that YOU want. If biology gave you three ears, be happy with that! It's YOU.
For decades, I wanted to sail around and adventure on the high seas. Once I got back to Canada, I did just that. It was expensive but I loved every second of scrubbing MY boat's deck, every scraped knuckle that MY boat gave me, and every sunset that me and MY boat shared each summer's day. I sold my boat now, because of Co.... you know... but I do have such great memories and photographs. And, should I be successful in robbing 3 banks, I will own another sailboat and sit on Lake Ontario again just to watch the clouds drift by.
That's what life (for me) is for.
YOU do the same thing. If you want to move your left ear to the top of your head, then THAT is your sailboat! I'm behind your decision with all my heart.
Live long and prosper, my friend.
