Wilderness just behind your house - allow a piece of wilderness to grow in your garden
Happy children need to be strong and healthy. Happy children hence need adventure and nature - just outside the home rather than once a year during a vacation. Living countryside offers all the adventure children love - wild animals, plants, trees and plenty of fruits free to pick whenever hungry for vitamins and tasty delicious sweets may by God.
Hence a family - husband wife - can be much easier happy when both know for sure that their children are happy, fulfilled and among loving healthy friends ready to share adventures and life in a rural community. Mountains and wild nature is most valuable when just within easy reach of all family. Wild nature - wild forest or wild jungle - is a natural God-made resource of life-force and healing power - life-force in abundance is needed for an active fun life. The most ideal situation is - like here on the photo - to have large junks of true wilderness just outside your doorsteps, around your homes, amidst all village and houses as a natural playground for pets and children, as a natural habitat for all animals nearby - animals to become your children's pets and best friends while living in freedom.
Happiness between husband and wife never shall be possible as long as children live in a prison like city or corporate environment - happiness of all parents depends on happiness of their children as well - happiness at any cost and price - even if it may require a much simpler but natural life in a natural environment where health and freedom are given to all by default - as a God created gift to all.
