What am I really like?

Normally, when I think of myself, I think of all the things I can/should improve about myself. For example, learning more, understanding better, being less hot-headed, relaxing more, etc. It's a little hard for me to see the good about me. Most likely due to a large insecurity that I have about myself. Yet another thing I need to improve about myself. Well, I finally got to get a glimpse of what other people around me think of me. In my opinion, that's always a good thing. I don't think it's a good thing if you think you're so perfect, or if you think you're a complete mess.
Two days ago, we were having dinner at the in-laws with the rest of the family. It came up that my sister-in-law thought I was the best sister-in-law ever. *tear* All of a sudden, it came out as to when my MIL and SIL realized I was a good person. First, we were talking about how I didn't give off a very good impression the very first time I met them. I was very nervous and a little irritated that my now-husband had invited me to meet the WHOLE family at a last minute dinner with no way to get around it.
My MIL then told me that the first time she realized I was a good person was at my BIL's wedding. I was actually very, very surprised. My BIL's wedding was very early on in our relationship. I remember the wedding being pretty hectic and voluntarily helping the girls out. I had felt surprisingly comfortable that day and was completely myself. I had a great time running around and helping them out. Not once did I think about what would or wouldn't impress his family.
Then my MIL told me that the second thing that really confirmed that I'm a good person was when she met my parents. I love my parents. I truly believe that they taught me how to be the best person I can be. Apparently it shows.
Finding out what my in-laws thought about me and how much they really did think I was a genuinely good person made me feel great. That must mean I'm doing something right.
