why?

Did I cut my hair? We came back from Florida, my hair was below my shoulder blades, Japan was a furnace and I chopped my hair off. I took this picture the day after the initial cut. Really, it was all a mistake. The guy was cutting layers into my hair that were too short, already the length you see above and the shoulder length hair I was going for was looking pretty yuck. I have hence decided, with the approval of husband, that I will no longer do this. Its another pattern of repeated behavior that always ends with the same result...WHY?

I got a little adventurous this summer and started cutting up shirts and sewing different things. This shirt I cut right down the middle. For some reason this shirt has not stopped shrinking and continues to shrink every time I wash it. I liked wearing it this way, but unfortunately it continued to shrink and I don't think will fit around my arms anymore. More why?
