Haha, I feel like I'm swimming through spiked molasses, sometimes.
I'm scared of being rude. There's various people that I'm afraid I've offended. And often, I forget to try to think of other people's feelings, instead just acting on my own. I'm trying to live a more disciplined life--not discipline for the sake of discipline, but because there are so many important things I still haven't mastered or understood.
I guess it's that I'm trying to be good, but sometimes I feel that I don't even know how. And I expect more of myself than that.
While I'm a little uncomfortable offering advice to someone I don't really know well, I feel that in this case a bit of general comment might be useful.
Everyone is different, and unless you happen to intimately know the insides out of another's personality, it's inevitable that you'll offend someone in someway, intentionally or otherwise. You should try to avoid catering your behaviour for someone else, unless it's your job or whatever, because it'll just make you unhappy. If someone
should be offended by something you say or do, it's their problem. If they want to make a deal of it, unless you were trying to get their back up in the first place, the only thing you can really do is apologise, and perhaps offer an explanation as to what offended them.
Bear in mind, I'm super-biased in this. I'm an introvert, and I really don't like communicating with people. I had spent a fair chunk of my relatively short life trying to make everyone else feel good, and not really thinking about what
I needed or wanted, and consequently got into the mindset that I wasn't really worth anything. It's not really something I wish on anyone.
On a side-note, you can't know everything there is to know about everything
life is a learning experience, from start to end. There will be things you find that you're good at, perhaps better than most, and other things that you can't seem to get your head round no matter how hard you try. The trick is, I think, being slightly biased toward yourself. Live for yourself more than others, but remember that friends and family are always good too.
