Basically, would you rather bet on the same thing again and again then regret not exploring more or explore different kinds of bets then miss out on a win?
Hmm, that is a hard one, because both scenarios look pretty bad. I guess to change the set of numbers just to see it being the correct numbers of the next draw is the most painful alternative in this case, because you were close of the winning, and somehow it slipped away from your hands so close of touching it. It's worse to deal with the fact you were almost achieving something than having the perception it has never been close to you at all.
