It is important to stay united among siblings.
As the old saying goes… well, I don’t know what is the old saying actually…
But I have heard of the story of a single chopstick that can easily be broken while a bunch of chopsticks will not.
In short, a family is actually like a company. If a company cannot function as a unit, they will not be competitive and eventually have to be dissolved. Same for a family. If the family is not united, there can be many selfish disputes over trivial matters. And eventually the family will split.
However, the opposite is true. If a company has employees that are totally united and work for the benefit of the company, the company, through selfless contributions, will eventually prosper and so does the bonuses of individuals.
As for a family, if the family members stay united and work together to keep the family close knitted, then the relationship will blossom and everyone will be emotionally accomplished. If the family works together, through synergy and selfless contributions, the family will prosper much faster than a family of solo effort.
Do the math and one can see easily that unity beats solitary.
