You are very busy.
You have too less time to rest.
So you are tired.
With only 5 minutes, you could refresh and balance your body and your mind to work better and think more clearly.
"5 minutes for mind" is a simple tool that could help you remember and perform some easy and suitable changes to refresh your mind and your body. (It may be a first step to know a performance of meditation (title of japanese is Zen))
