I had similar thoughts as well at first. I chafed against the effort involved in dressing better, being more sociable, and a whole range of other habits. The surprising discovery I made in that case was that I started to like things I previously disliked (certain types of social activities) and lost interest in things I previously spent a lot of time on (mostly escapism). As I engaged more with the world my attitude changed, even though I retained the same core personality. I effectively passed a threshold beyond which the effort started to pay off in terms of satisfaction, to the point where it no longer seemed like a burden at all.

Of course, this is only my own experience and will not be relevant for most people. However, it's certainly a counter-intuitive notion that merits investigation. At the very least, it's quite helpful to critically evaluate your most common habits and patterns.
