The self-summary is hard to fill out because it feels too vague. You could think of it as a brief description, but of what? My appearance? My personality? I have pictures of what I look like, and my personality is not something that I personally like to package into gift wrapped boxes like INFP or EMTJ. Plus, I feel I am whatever the people that know me think of me as because it's that perspective that is important. Those people get a sense of who I am by what I do and say and how I interact with them.
I guess what I'm saying is that I could say that I am a silly, intelligent, caring, thoughtful, funny, sometimes geeky, shy, artist, engineer, but that's really just a tag-line. And you'll get better sense of who I am, hopefully, from the little bit that I've written here, and by actually talking and interacting with me.
Having said all that, I feel it's only fair to admit that it is often hard to get to know me, mostly because its often challenging to start conversations with people I am unfamiliar with. Although I have developed really close rewarding relationships with the people in my life.
