Better too much a plan than little,
Actions overflow from thinking,
Finer plans give visions their mettle,
Clear details keep dreams from sinking.

But it's likely that most things never take shape in the mind clearly enough to get started, too. That's what we're hitting at today.
Which do you think is the greater need, to jump in and not worry with the details, or take care to have plenty of specifics before beginning?
