Mine is not so much a drive to "make" things, as a drive to learn---how to do things, how things work, how things are made and used, and then maybe try my hand at it myself. I think we all have a "drive" force/energy within us that we channel into something---be that sports, hobbies, music, dancing, work, etc... and I think that those of you who "make" things have found a fairly steady way of utilizing that energy, and do so as your method of channeling that interest, drive, and energy in a fashion that appeases you, at least temporarily until the next challenge or idea comes along. And like everything in life, the more you make or learn about something, the more you realize how much more there is about that topic to learn or how much better or different you could make that product, which then simply becomes a self-repeating and self-fulfilling proposition, the slippery slope many of us willingly go down as far as we each may possibly go. That is why there are so many good---no---great artisans on this forum, and great thinkers and great teachers and great collectors of knowledge. Some may reach their ultimate fullfillment, others not, some continue searching for the path toward theirs, still others realizing the goal ever-being just out of reach, allowing them to continue along that path ever further, is their own fulfillment of sorts.

Wow, where did that bit of literary flight of ideas philosophy come from?
