Think of it this way. In order, from best to worst:
1. You lead with words, they are followed up by consistent action.
2. You say nothing, and do nothing.
3. You lead with words, and then you do NOT follow up by action consistent with those words.
In other words, it would be better to say (and even do) NOTHING, than to make vainglorious "grand pronouncements" and phony boundaries, only to then not follow thru on them.
