Luck

I had always believed that I was lucky. Maybe, I was. But, I don't really remember any instance where luck gave me a boost. You might say, I was lucky not to be crushed by a truck in a street accident. True, things could get far worse, but what I feel is that whatever happened were destined to happen, just the sun rises everyday, and all these were definitely the worst of the things that could possibly happen. I never got what I wanted, whatever I got was the least that I could expect, but still I slowly learnt to be happy with whatever I got, despite my firm belief thats its much less than what I deserve.
This feeling makes me think if there is at all any point in even talking about luck. Is it rational to say, "whatever happened happened, and couldn't have happened any other way."?
