A good space needs some emptiness.

Happiness is elusive, small, fleeting.

Idea that happiness comes from the negation of noise and ecumbrance, not from a postive addition of things or even emotions. The need for absence for the mind to re-calibrate, re-compose itself , thus creating happiness: super-structures need a vacuum (empty space) to breathe, space to put elements on the side. The more elements, the more space needed.

A starting point for the feeling of happiness thus comes from small elements, a small positive recombination: a physical ease combined with a sight of something that works, a puzzle solved, a miracle of Nature that not only hypnotises us and make us dream and soothes us but more importantly  takes everything away and pushes the image of a large space in our mind, a sort of 'here you go, there is space, you _have_ space'. 

Loneliness and sadness comes from beeing in an unconnected void, not seeing the links tying the space to all elements. 

A small sparkle from a small image is enough, like a fractal image, it has contagious effects.

Space and time, you have space and time.
