we are more than this

I was on my morning walk one day and just mindfully observing everything that’s around me.  I noticed that every plant that wanted to survive, will sprout through the cracks of the roof of houses or sidewalks.  Even an injured bird, would still try its efforts to jump up the curb.  There was so much evidence of the strong will to survive from nature itself.  Hence, how are we humans, who are supposed to be of higher intelligence than nature, be happily confining ourselves to what we were told we can do or cannot do?
