Plus One for what Indy said. I haven't connected with or met any of my co-workers that I've read about on our intranet, but I have been inspired by them. There was the lady that was 100lbs overweight who went to the Boston Marathon and decided right then and there she was going to run that race and sure enough the following year she had lost the weight and run that race.

I also agree that you don't need to give an indepth look at your innermost being. Just be yourself and share you passion like you would with anyone else who asked you about it.
