Build The Muscle of Self Esteem

So why is it that so often, when presenting personal development workshops and the like, I keep meeting people who have a particular goal in mind, their ultimate goal, but do NOT wish to create baby goals for their personal growth (confidence, self esteem, assertiveness, etc.) in order to build the muscle? I say to students, "build a list of all your good qualities and achievements and read it to yourself every day for one week" - very simple and anyone can do it. Yet a week later they want the next step to being successful and confident but haven't taken the initial step to build the muscle of self-esteem...?!

I'm just thinking out load now but maybe people think they are already at an intermediate stage in their personal growth, so they do not need the baby steps - or to use our earlier analogy, they feel they need larger weights to be challenged?
