Quite the tight rope to walk.
But, alas, we walk it.
Inspiration is what needs to be defined here. Inspiration has the potential to come from even the smallest molecule of energy, thought, or theory. It doesn't have to be one kick in the bum. It's the act of creation that should be inspiration to others that they too must be creators. If you're not creating anything, then you're just taking stock of other people's pasture. It might just be a sad attempt at emulating the vastness of being God, but it's all there is. So, keep doing what you're doing, and at the end of the day, even if your sandcastle fades with the skyline, the memory remains. That's one more point for humanity.
