Is life complicated?...

This question came up at a dinner conversation very recently. This really got me thinking. What makes people think that life is complicated? What factors make it complicated? How can one quantify the complexity of life? What is it in a "life" that makes it complicated? The more I thought about these questions, I realized that it all boils down to one single factor. Its the people themselves. Its you and I who has the power to make life easy or complicated. Why blame it on external factors when one has the power within oneself to control ones own destiny?
There used to be times, when I used to think why life should be so complicated. I used to contemplate over things that I thought made my life complicated. Over a period of time, I realized that it is the choices one makes in every step of life that determines how easy or hard ones life can be. The decisions people make are always not right. Some decisions becomes a turning point for some people after which there is no looking back. It does not necessarily mean that their life has become a cake walk. But it is the choice that he/she made to go around that turning point makes it all worthwhile.
I strongly believe that there is no use in crying over spilt milk. You take decisions in life and live with it. Some turns out to be wise, some stupid. You cherish the wise ones and put up with stupid ones. But at the end, its in ones own hands to make ones life complicated or easy.
