For whatever reason, this topic struck a cord with me and motivated me to point out some things that would, for me at least, really help a proposal stand out from the crowd.  

When I receive a gift certificate to the local grocery store, I can immediately put it to good use, but it doesn't stand out as a gift.So, for these reasons, tangible items are sometimes the best .... they can sometimes spark a smile or warm a heart on the spot... especially the ones with a personal touch.
