Aim nothing- Achieve everything

One day I start dreaming to do that and achieve that aim for the thing and go for it. That person has that car those people have big houses. Not only me but i think everyone, and finally when we fail and got disheartened and get dipressed.
But why we think why we aim why we want more, its very easy to be happy with what we have. Enjoy the things we have, the time we have, life we get.

In the end just go for nothing, you will achieve everything
