Where are we heading to...

I've all the time wondering where are we heading to in this world. Are we heading to self satisfaction, self stability or financial capability ? Do you really satisfy with yourself now, I myself have yet to reach that situation. I've to work even though up to the age of almost half a century. I've seen others are trying their very best to support their family and relatives to live not forever in this world. But all of us know that we are not here up to 200 years even some may say that we human can live up to 150 to 300 years with the recent medical development result. So where are we heading to ? We ought to find ways and means how to make ourselve and others to feel that we are here in this world with a definite reason, with a clearly defined aim and with sole destination ...
otherwise we are nowhere we are nothing and aimless. Thus I think we should be motivated to encourage ourselve to pursue a research on what worth are we living in this world. Are we like animals that live without proper laws except for symbiosis interaction, predator-prey inter-relatio n of course not! So where are we after ?
