Explain why you feel Earth's gravitational force but not the gravitational force exerted by a book?

Because there's such a difference between the strengths of the two forces.
The gravitational force between two masses is proportional to the product of the masses.
So if one mass is constant, then the force is proportional to the other mass. Also, the force
is inversely proportional to the square of the distance between the two masses.
Let's say the book has a mass of 1 kg, and is one meter from you.
The earth's mass is 5.97 x 1024 kg, and it's centered 6,378,000 meters from you (earth's radius).
So the ratio of the (gravitational force toward the earth) to the (gravitational force toward the book) is
(5.97 x 1024)/ (6.378 x 106)2 = 1.468 x 1011
The gravitational force between you and the earth is about 147 billion times as strong as
the force between you and the book !
If you weigh a ton (2,000 lbs), then the force between you and the book is like 0.000000218 ounce.

What is an gravitational force exerted on an object?
The gravitational force exerted on an object, according to classical mechanics, is the product of the gravitational constant, the object's mass, and the mass of the object exerting the gravitational force divided by the square of the magnitude of the position vector starting from the object exerting the gravitational force and pointing to the object which we are measuring the force exerted onto. And all of this is times the negative of that same position vector.
