circle of life

today people might say life is like a movie. good or evil might be evil. babies come to the world connect with their inner self, their need, the body language of the people around them that's the ways the lear to live. but as years go through feelings, sensations, needs are left behind and now is the time of technology, to each other is old-fashioned, looking into somebodies eyes, get a real connection, writing down memories a dairy.

we need to back to real connections, caring about people around you and spending quality time with them. we need to find back the way to connect with ourselfs, let out our emotions, sensations, our real tastes without caring about what other might think/say about,but especially without judging others way of living, feeling and loving.  

as we grow we lose our ties with our real selves, and we get too much involved with media, work, politics. we become so much troubled that our energy vanishes away and we only have the disposition to sit in front of the tv on turn off ourselves.   that's unbearable, we need to find out the way not to lose ourselves on the road to adulthood. but especially we have to find a way to keep children on the track. it would be easier for them when they grow ´s a lot of people on that track you just need to keep your eyes wide open and you´ll see it.
