I know someone who intentionally and successfully won small cash prizes four times in a row (I believe those scratch cards that you buy, or something similar). I have never met anyone even like this person. According to this person, attempting such a feat with large lotteries with gigantic cash prizes is in a whole different league, and says that to do so would be to compete against the awarenesses of millions of others. This person further states that one cannot force or rush those small cash prize winnings, let alone larger ones.
And to me, this person is in a league above everybody I've ever met, and could barely scrape up some small winnings.
Perhaps that will put things into perspective
