Answer:
A positive relationship or a happy relationship definitely has a positive effect on the environment. In what sense?
The brain naturally could sense the positivity or negativity in us, a home where they're always arguing, or exchanging foul words and beatings, the victim spouse and the children in there can't have peace of mind, there'll be setback in their communication within themselves(and communication is the first agent in building a rigid and positive relationship), if there's no one to share their pains, may lead to depression as they'll keep thinking over and over wishing they'd the best(of spouse or happy home).
So, If a family is happy and relatives have a great relationship, they can help one another in achieving the best in life not just in academics, they'll be free to one another, meet each other easily, share pains and rub mind together and this will bring success because in life one person can do it all. He or she need supporters as a bunch of broom isn't easy to break and can make a clean job whereas a stick of broom can't achieve that.
