challenge
"A great challenge is like a great romance. It calls for your passion and your devotion, and it demands to be the center of your attention. Rising to meet a challenge is a form of seduction. It means concentrating your energy and resources on what's most important: keeping the fire burning!"
"Challenge means something that is difficult but with God's help its possible! Challenge is like climbing to the top of the mountain. It is hard but possible."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
