They say not to pick your own tickets like using birthdays and anneversaries and ect. Because those numbers add up to 1-32 and the numbers range 1-69 and even though u might use numbers 32-69 by your year you were born, you would only use a big number once or twice saying its annerversary or birthday .so the other 3 numbers your leaving out the chance for it to be 1-69 .
