For me it was when sometime during year 1 I went back to visit my family in the Midwest and we spent some time at a relative's house. My mom and sister both later told me what a change they saw in me, that I was mingling around the house looking people in the eye and actually conversing instead of staring at the floor and mumbling one-syllable answers like I always had in the past.

Then along the way in different increments I got a new job, got promoted, moved to a nicer house, got another new position, did a training I'd wanted to do, went back to school.... of course this is all over a 6 years period.
