No, I still think many of us give up too soon... Winners in general do things just a little different and that's all. I don't think 'luck' has anything to do with it. Sorry...I don't believe in having luck at all!
My own personal life has been about 50/50 mix....half detemination and half luck.
1. Meeting my wife - luck. Getting her to marry me - determination.
2. Getting to the school I want - determination. Graduation from the school - luck.
3. Getting my job when there were well over 100 applicants applying - 50/50. Finding the position posted on a newspaper that was left on a Subway's restaurant - luck.
I can go on and on.....but that's me....some things in life you can work on hard. However, other things you have no control over...I call it luck if it's positive.
