We always think that the grass is greener on the other side. We live our lives as if on a runaway train, travelling on and on the hope of finding a beter., Worm, grander station. Oddly, all the stations we stop at are  never quite what  we thought or hope they would be, leaving us empty and unsatisfied. 

so often the best green grass is right under our feet. That is not to say that we should not look for best opportunities or settle for an average life you are not happy with. Sometimes the key to a happy life is just to be content with who we are and to live our life with heightened awareness of grasping the opportunities where we are at the moment.
