When we feel confident, it's tempting to give advice, or in many cases, to start taking care of others. Be careful -this can be dangerous. There is no certainty that our health tomorrow will be the same as today; we must always maintain a humble attitude and serve our bodies each day. That natural human laziness can be overcome with a tiny bit of discipline. Avoid taking care of others in place of yourself. If you live according to this maxim, you will ultimately be a better friend, as you will be available and strong in times of crisis and need.
