Your text is sensational. I usually say that health is the most important thing we have in our possession, without it, we can't do anything else, so it's essential that we take care of it.
Although I confess that I'm not taking such good care of mine, what I have been doing is trying to cut out too much sugar and salt, after all, balance is what matters, we don't need to deprive ourselves of everything, we just don't need to consume too much of anything.
Now, about "Control What You Can", it's perfect, I used to want to control everything all the time and that's horrible, so now I live a lighter life, worrying only about what I really need to worry about.
