I agree with this guy: I think you make your own luck.
If you take aggregate effort in a community and average it out, then there's an equal probability of that special event happening to anyone. If however you are that person who puts in the extra effort and brings up the average, you are turning the odds in your favour and increasing the likelihood that the special event actually happens to you.
Think of it as everyone buying one lottery ticket, but you buy more than one... your odds of success are proportional to the effort you've put in.
Thoughts?
