"Which of the 5S is most difficult?" I received this question during a class I was teaching recently. I've never been asked this before. People often say "self-discipline is the most difficult" or "sustaining is the most difficult" but this answer never really satisfied me, so after a pause I gave my answer to the students.
In my view it's one of the other 4S that is the most difficult. I won't say what answer I gave, or why, quite yet. Let's make this a 5S Challenge.
