This book was created so that you can admire the gold ring on the ring finger of your right hand for as long as possible. And if you only dream about it, this is also a very opportune opportunity for you to go through the “School of Love” and master the science called “Happy Marriage”! And in order to make it easier and simpler for you to study these sciences of life, here is a Textbook for you. Everything in it is real: there are lectures, questions from the spot, problems, and solutions. It is written like the Criminal Code - according to precedents and for all occasions in life. You can learn from other people's mistakes, take note of other people's enlightenments, and only in one thing will you have to go through serious independent work - in building your own life, unlike anyone else's! Act as love and your heart tell you, even if someone’s advice seems successful to you (including highly professional advice) - listen to your heart, like a barometer: is this your path? I wish you the ability to love and unconditional love! And then you you will see happiness.
