Child rearing is very hard work.It will continue at least 20 years.
In addition,it takes a lot of money.
But your parent did it for you without return.
They had been worried about you,your health,school record,
money,bad boy or girlfriend you loved,stupid fashion,a period of rebelliousness and so on.
They may cried many times because of you or
they may had a slight mental problems because of you.
But they managed somehow.They protected you in many ways.
Their act is God itself.
(Of course your all ancestors did same thing in spite of poor situation)
Your parent is God.
When you realize the fact,your life will be changed significantly.
I know some people have a trouble with their parent.
And there are bad parents in the world.
But most important thing is parents already did all things you need.
And they gave you a chance of life on the Earth.
You need to know the process of pregnancy of human.
When you were a baby,you were the weakest human in the world.
Parents protected you.
You don't have to love your parent if they did bad things to you.(Abuse,Neglect)
But don't stare at only bad things.
You need to think about whole things.
When you get a job,you will generally use the money only for you.(1st step)
Next,if you are promoted,you will use the money for your family and enjoy good and luxury life style.(2nd step)
But if you become BIG successful in business and become richest,you don't want to enjoy luxury life any more.You will realize it is meaningless.
You will want to use the money for society or growing people.(3rd final step)
Raising child is same as the 3rd step.
Even though mom doesn't experience 1st and 2nd processes.
