...nothing in relation to what surrounds you.
I'd disagree. Each person can achieve an incredible amount and what that may build up to may certainly be a critical block in the fabric of time. That block may seem minor now, but could amount, through a snow ball effect of the events it causes, to something incredible through its impact on events in succeeding years, decades, or even centuries.
of course @hatu. i don't deny that. but these numbers, this huge universe - it shows us how small we are. even insignificant in relation to the universe itself.
but in our own world here on earth, it looks quite different again.
once to look at the big whole can never hurt and could perhaps even open us for new things. who knows ;)
