There is a saying that 50% of people will like you, and 50% of people will dislike you. Sayings like these can prompt one to consider the law of averages.
Briefly stated, the more you do something or the more you have of something, the better your chances are on averages. It's basically a numbers game.
Many like to put the law of averages in practice when they gamble. This could even be a raffle or playing the lottery. The more tickets you buy, the better your chances are.
Life really is a gamble anyways. Proper usage of The Law Of Averages can tip the scales in your favor.
If you're looking for a job, you want to apply to as many places and opportunities as possible. It can also make rejection hurt less. Options are always great.
There are many (especially men) that use the law when dating and finding that special someone. They talk to as many people as possible, go out on dates, socialize and such. Dating sites and speed dating events were designed with averages in mind.
The Law of Averages is not much different from practice and repetition. Often the best way to learn or master a craft or a skill is to put it to use. The more you do it, the better you can become.
The principles and examples I have outlined can be used for good and evil. Let's hope that more people will use them for positive benefits.
