green. yellow. green. there's no red light

i like this picture a lot.
quite meaningful.
everything is conventional.
e.g. what makes "green" - green?
why we move on "green" signal and "red" one makes us stop?
well, its not the question about traffic lights, though:)

another question of my concern at the moment - "cross-roads", choosing directions.
and about enjoying what you have. all books claim that you have to see positive spark in everything. Appreciate things you have. well, i do. but it seems to be problematic as well... since some people see discrepancy between appreciating things you've got and struggling for more.

i am bit confused :) though i love how things are developing at the moment...

Some people want it to happen, some wish it would happen, others make it happen.
