How do I learn to deal and accept my family for who they are?

I'm very pleased with where I am in my life, and super excited about all that Ive been able to accomplish. I don't take myself very seriously and I'm very humble and also goofy and silly at times. Whenever I'm around my extended family they ask me questions about my life as if their interviewing me. I feel like they are trying to make me understand that my life isn't as good as it seems to me. I'm pretty content with the way things are in my and I don't really plan on making any major changes to what I'm doing. I feel like my relatives always try to show me up and brag about their successes, which I think are great, but I'm pretty humble so I don't brag back or boast about what I've done. How do I leave family gatherings without doubting myself and what I do. I would never really change myself just because of someone else's thoughts, so how do I deel with the feeling?
