Exploration, Hobby and Madness

Imagine humans staying in the same place for centuries. It is not even possible to imagine.
Imagine a mouse in a box. It will not move for reasonable time, till it gets the perception of being safe.
The safety is the main issue.
Once it feels to start that it is safe, it starts to move.
But, Move for what?
This is the primary question in my mind for today.
Take an example: For food.
For better food!
Once it starts to learn the term "better" in its mind, it becomes active. More active. It starts to think. (I am trying to draw parallel to human, so please bear with me.)

We are driven by some motivation. Some kind of curiosity. This is the father of the exploration.

How do we define the degree of curiosity for individuals? because the amount(quantity?) of motivation is different for each of us.
We all live in our own universe. Your Universe overlaps with my one, at some points, so we have some kinda interaction.
No one knows what s/he will get the next moment. But not everyone explores. It is interesting human behavior.
But once s/he enjoys the joy of exploration, it becomes hobby. And for someone who have not been infected with such curiosity, it is termed madness.

I was walking on the Road, covered with the snow. Since there had been a strong storm, no one had walked on the road. I was putting the first steps over the snowy path.
I enjoyed it.
Think of Armstrong! He did something which no other Homo sapiens had done. To put the feet on the Moon.
Is it a madness or hobby or exploration or a mere duty?

Can you imagine the joy of that?
