I used to sweat the small things at work, and stress follows, now I still look at the smaller things but do not sweat over it anymore.
In contrast, I used not to be able to sweat much in the gym and it is not healthy, but now I sweat a lot on workouts.
I found that sweating is really healthy, and the body is capable of adapting and liking it a lot more - its not about losing weight or water, but about working for it.
The idea of sweating it out has a great meaning - working hard over something!
