fluctuation

It's damn irritating to have fluctuation, 2 things in particular. My weight and my capabilities in martial arts.

My weight always go up and down, despite I did nothing to affect it. I eat normally, bowel movement still as good as ever, whole bunch of vitamins and other minerals. My weight still goes up and down, what is fucking wrong with my weight?

Then there is my martial arts standard. Sometime I can punch very fast, sometime the speed drops. I really hate that my punching speed drops. My kicking also fluctuates a lot, some time can be high and fast, some time it's just simply like shit.

Fuck! Please, stop fluctuating, I didn't do nothing to affect it, so just fucking stop.
