All things potty....

Ok, Logan turned 3 at the beginning of April. He has had absolutely no interest in potty training. My doctor has simply said "If he fights you on it, wait...don't force him." That's easy for him to say! He's not getting the pressure from all directions. I can't tell you how many times people say to me "Well, it's all you. You have to train yourself to take him." (Like I don't spend half of my day trying to get him to use the stupid potty!!!!) Also equally annoying "Well ____ is just about his age and he/she is totally potty trained." (Like I'm the worst mom ever because my kid doesn't quite get it) I have tried to gently get him to do it, but it has been met with equal resistance.
Today I made the goal that Logan is going to wear only "big boy pants" and we were going to get this done. He is still laying on the floor screaming "You're terri-bo(terrible). I want my DADDY!"
I am starting to think that this is never going to happen.
Does anybody have any tips or ideas?

@!$%^&*

Does anyone have any suggestions as to how to get a child to quit saying a "naughty" word? Our next neighbors are "classy" and use the f-bomb all the time. The problem is that they scream all of the time. Logan has learned this word and now uses it A LOT! I have tried ignoring him, I have explained that we don't use words like this, I have done time out, nothing seems to work. Every time these idiots start screaming, Logan starts to say this word! (I just feel like the worst mother ever. I was 12 before I even knew that word!)
