There are two levels of "letting yourself go," according to a well-known expert on the subject (that would be me).

The Two Levels Of Letting Yourself Go:

1) Letting your body go (not eating healthily, gaining weight).
2) Letting everything else go (e.g. not making an effort to wear something that looks remotely nice, not showering regularly, not taming your hair, etc.).

I did both for a while, but started taking better care of my body a few years ago. I'm kicking up the self-improvement efforts on that front now, but am also making an effort to shower more often and to dress better too. I even wear a blazer out most days, instead of the puffy jacket I used to wear.

I find that I'm less embarrassed when I run into people on the street lately. Progress?

How about you: have you struggled with letting yourself go at all?
