Kismet-Karma

Kismet, Fate, Luck or chance or destiny... all these are perhaps similar sounding words. I don't know exactly what do these words mean. Have never believed in something called as luck, because for me it was all the result of your deeds. Whatever I got in my life was mainly a result of my hard work, my deeds.Hence for me Karma was more important than Kismet. But in past one year this definition seems to change. Today I have started believing in Fate. I have seen if your luck is not with you, no matter how hard you tries, how good your deeds are, how noble your intentions are nothing can happen. You cant get the desirable thing in life if your luck is not with you. Hence I am forced to think that what is the benefit of fighting so hard in life. If everything is pre-decided for you then why should you worry about the future. And I am forced to think- Is it Karma or Kismet that affects your life, the most?? Two quotes with which I would like to end- " Never take life too seriously, no one comes out alive from it" " Life can change in a Blink, but God seldom Blinks"
