Although picking hot numbers and avoiding cold numbers may give you a slight advantage the real benefit of using a lottery system lies in its ability to slash the odds against you winning prizes by allowing you to pick more numbers than usual and then wheeling those numbers in a way that gives you many more chances of landing multiple wins in the same game.
This question is without a doubt the number one topic in our industry. It's also the subject of various "secret systems", scams, tacky books and "special reports" – all of which are total bunk. The simple fact of the matter is there is no guaranteed way to win the lottery. If there were then lotteries would have absolutely no reason to exist (and I'd be sprawled out on the beach at some exclusive resort in Fiji sipping a mojito right about now).
Choose a lucky number and stick with it. Some people choose a number sequence that they consider lucky and play it over and over again until it comes up a winner -- if it ever does. For instance, if you’re favorite number sequence is your favorite number, combined with your birthday and your spouse’s lucky number and birthday (3-6-11-9-10-31), then you would play this number religiously every time you play the lottery. Then, you wait for your number to come up a winner. This could be considered making your own luck.
