Do I ever get to where its second nature to eat healthy?

That is what my neighbor Steve asked me today after my run. He was out washing his car, I was limping back from the run. ( I will get back to that limp) . Anyway, He asks me questions all the time about weight loss. He is in his sixties, single, and wants to lose weight. He asks me what I eat , how much I exercise, he is interested, you can see the wheels turning, but he hasnt gotten it into motion yet. Anyway. He today he stopped me as I was passing his house and said " Silly question to ask you Tami, But do you get to the point where you dont have to think about eating healthy, and you just do it" ? yes, I told him, I am at the point where my first choice , is a healthy one. but how I eat today is certainly different than how I did even 1 year ago, 6 months INTO the weight loss. So as we talked, I was saying I wonder if I will get to the point that I wont be frustrated with how slow these last 17 pounds are coming off. ( only lost 3 pounds last month) . I told Steve that, and he said he would be so happy to lose 3 pounds a month, cause that would be 36 pounds in a year! I was so happy that he thought of it like that, GOOD FOR YOU STEVE!!!! But what bugs the HECK out of me is that I am working HARDER than I did a year ago, when I was losing 2 pounds PER WEEK, and eating better than I did then, and I am busting my butt to lose 3 pounds in one month?? I WANT TO BE DONE!!! not so I can stop working out, ( cause I can tell you right now, I am addicted to working out, so I wont be stopping ) and not so I can eat more ( but it will be nice to increase the calories a tad) but so I can stop having it hang over my head. I want to say " I achieved my weight loss goal" and I am now maintaining my weight. I want to say " I have no more weight to lose" for the first time in MY LIFE, I want to be able to say that!! I want to be a size 7/8 and lose these last 17 pounds.

Back to the limp. the moment I started running today I felt a pain in my right hamstring. I kept running, cause often times when I start running, I have some aches and pains. But this one kept going. But so did I. the hills really hurt, and I did stop and walk one of them, I even kind of limped and ran for a while. all the while I kept thinking " when is it not right to push thru the pain" and I kept wondering that, while I kept running. the pain gets worse with each passing hour.
