I get along just fine with most people. The instances where I outright clash with someone are fairly rare. However, I know I tend to be overwhelming for some people with my endless stream of seemingly impractical, loud voice (I can't control my vocal volume most of the time), wackiness, disinterest in conformity, scattered behavior, and probably other things I can't think of right now.
This was more true when I was younger.
So, I guess I could be considered difficult. On the other hand, I'm usually easy-going, a hard worker, friendly, and willing to listen to new ideas and perspectives. So, a lot of parts of me don't qualify as what you would see in a difficult person.
