I think you did the right thing too. There are times when you just know that it's not a good idea; listen to that voice. There will also be times when the conditions are borderline for your experience, you'll feel confident, and you'll expand your experience level by flying.

I consider myself a half way decent, intermediate pilot, and have learned to judge by the swaying of the trees when I shouldn't even bother going to the field. I also watch the weather reports, and if they say 15 to 20 mph winds I don't go. If they say 10 to 15, it'll depend on how I feel and what I have ready to fly.
