Answer: Here's a Few Hints
Step-by-step explanation:
While, of course, I cannot write your assignment for you, I can give you a few pointers.
1. Remember you teacher's going to read this -- don't be TOO detailed (i.e. bathroom habits) but, at the same time, put in enough details that they know you made an effort (i.e. include what you eat, how much sleep you got, a meditation excersise you tried, etc.)
2. Don't exagerate too much. If you don't make efforts to stay healthy irl, don't write about them here!! Your teacher knows you...
3. Keep it casual! (Teachers usually give assignments like this for easy grading -- don't make it too hard on them.)
4. Consider formatting it like your day.
