A very powerful way to join ideas together is to make a Metaphor. One can create this "wonderful Harmony" simply by recognizing similarities between unrelated phenomena.
Dont throw away your potential to make a difference is like:
walking the extra mile
doing what is right
helping someone cross a road
saying no to drugs
choosing between life an death
walking while you can take a cab
starving while you can feast
fighting while you can ignore
saving instead of killing
fighting a war
