Navigating the world of meeting and dating women can be a perilous journey, one which is often learned through brutal personal experience, sometimes aided by the advice of other men or female friends.

Well we never really bothered to consider the relationship advice of children. And yet a pre-pubescent boy has now figured it all out - and made a bestselling publication of his insights - into how to win over the ladies, and specifically, one special lady friend who will actually treat you well.

Alec Greven's 46-page book How to Talk to Girls has hit stores across the US and the 9-year-old schoolboy is wowing crowds on a national promotional tour, according to Colorado broadcaster 9NEWS.

In the book, Alec compares pretty girls to "cars that need a lot of oil."

"The best choice for most boys is a regular girl. Remember, some pretty girls are coldhearted when it comes to boys. Don't let them get to you," he wrote.

How to Talk to Girls began life as part of a creative writing project inGreven's 3rd grade c|ass. The resulting handwritten pamphlet was sold for $5 at the Soaring Hawk Elementary School book fair in Castle Rock, Colorado.

Described by the school's principal as "entertaining" and "timeless", Alec's work was a bestseller among students and parents before making the 9News bulletin.

Ellen Degeneres then interviewed the young author on her talk show and introduced him to HarperCollins Publishers.

"I never expected people to buy it like a regular book in a bookstore," Alec was quoted as saying in New York Post.

The reworked version, which also features his drawings, hints that being the smartest boy in the c|ass will have girls "prowling at your feet".

Other suggestions include "don't be a show off", "Control your hyperness (cut down on the sugar if you have to)", "go easy on the compliments to avoid looking desperate" and "comb your hair" while the best way to get noticed without drawing too much attention is approaching a girl with a simple "hi". "If I say hi and you say hi back, we're probably off to a good start," he said.

As for his own love life,he's singleat the moment. "I'm a little too young," he said.He says don't fall in love "until at least middle school".

He also offered this gem: dating (ie going out to dinner without your parents) is for "kind of old" people, who are 15 or 16.

He attributes his worldly knowledge to observation in the playground while his mother Erin says her son's wisdom comes from his love of reading.

The Facts of Life

Sometimes, you get a girl to like you, then she ditches you.

Life is hard, move on!

Tip: About 73 percent of regular girls ditch boys; 98 percent of pretty girls ditch boys.

Or sometimes it just doesn't work out.

I had a crush on a girl in preschool.

Then my family had to move, so I had to let her wash out of my mind.

You also have to be aware that girls win most of the arguments and have most of the power. If you know that now, things might be easier.

Finally, if you try for too many girls, you will have jealousy issues and might end up with nobody. It is really best to go for just one.

If you do get a girl to like you, that is victory.

Winning victory is a dream for most boys, but it is very rare.

What does it take to win victory?

I wonder what things will be like when he's all growed up.
