However much you indulge, pleasure does not bring satisfaction.
However good things may appear to be, they are not stable or reliable.
However things seem to appear, they do not exist in the way that they appear.
However much you are attached, that much you will suffer.
However much you engage in physical activity, that much you will be exhausted.
However much you talk, that many more concepts you will generate.
However much you think, it brings that much more uneasiness.
Always protect your mind.
— Mipham Rinpoche, Heart Advice
Gratitude to DEW for bringing this gem to my attention.
Great Middle Way 
“However much you engage in physical activity, that much you will be exhausted.”
I don’t understand this sentence- getting exercise is taking care of our bodies. I thought this would be an important aspect of our practice.
It is a reminder to not exceed our capacity in frivolus activity.
Thanks Tashi.
