Momentary Meaning of Life

Some people consider their purpose in life, things to achieve over the course of their life...
What about considering your purpose from moment to moment. Surely you can break down your purpose in the moment better than you can for your whole life, as it is more direct, and, you know pretty much that you will have the opportunity to act.
In regards to purposes over the course of life, for some you may never get the opportunity.
In regards to momentary purposes, you may ask yourself 'What is my purpose here?', and you may get an immediate answer.

Very joie de vivre! LOVE IT.

Just thought I should add, that, it is possible to have more than one momentary purpose at any given time...
That is to say, you may be multi-tasking, and your actions may have more than one purpose and more than one meaning...
