Itsy Bitsy Little Success!

I have this Flintstones shirt I always wear especially at home. It was very uncomfortable and tight against my back and bust area but I wore it anyway (this was in the beginning of Jan.). I tried it on this week, and there is no tightness whatsoever, it almost feels big on me if it weren't for my bust XD Needless to say it was very comfortable to wear, and some other shirts are fitting quite comfortably after they have been so tight on me. I don't think my measurements are accurate or where I'm getting smaller truthfully, but I'm just glad that I can fit into that shirt again ^^
Also, my arms used to feel super squishy and fat and I'm slowly watching them get less meaty and, I'm actually building muscle O_____O my arms feel so hard right now, I can't even believe it. Not a huuuuuge difference, but it's just those tiny things that give you an extra push to keep going.
Just the other day I posted a thread of how I was so unmotivated, but I feel great right now when I notice these tiny little changes
