For physical appearance, definitely height. I'm about 5'8" and would absolutely love an extra 3-4 inches. It makes such a huge difference in every realm of life. Behavior-wise, I procrastinate so god damn much it is ridiculous. I am incapable of studying for an exam at any point other than the night before. I have done well academically so far so I constantly think about how much better I could be with good study habits.
Focus If I could change something about my appearance, I would like to be a bit taller. I'm not short (5'9). Also, I am oddly proportioned for a guy, but this doesn't bother me. I have the legs of a guy who is 6'3 and the torso of midget, while having the shoulders of a linebacker. So it works out really. I have nice wide shoulders and a solid build, which I think trump scrawny, skinny tall guy most of the time. Other than that I wouldn't change a thing about my appearance. alt focus I have generalized anxiety and adhd. What this means is that in the moment I am fine, but once the moment passes I tend to ruminate on things and worry I should have done something differently, which leads to more anxiety. If I could do something, then shut my brain off life would be a lot better. Maybe I should start smoking weed.
