It sounds like you don't value what you do either. If you want other people to respect your choices, even your 'for now' choices, you gotta respect them.

But let's forget that for a moment. I Never made a great amount of money, but I Loved what I did. I know at times people looked a little...surprised? perhaps that I was doing what I was doing. But I was so satisfied with my work and my accomplishments there, no one could look down their nose at me. Money is one thing, but true job satisfaction is hard to quantify.

I certainly would put a positive spin on whatever you say to people. And really, in social situations, a smile goes a long way. You don't have to say a word to look like you are having a great time.
And one more thing, people love to talk about themselves, so if you get stuck- ask a question, seem interested in their 'fascinating' world. They will think you are brilliant & have wonderful taste. And are very clever....

Best of luck to you
