think for the future, not for yourself.

if a person make one child educated, he makes a whole family aware of education and mean while, he taught a whole society and country and whole world. you love the chain i think.
help the poor and helpless children to get education and know some thing about the happening around the world.
i gonna quote a sentence from ILLUMINATI

"A society grows great when old men plant trees whose shade they know they shall never sit in."

so i gonna interpret it by my own. if we apply it on the children, it will be like " A society grows great when a parent educates his child whose earnings he/she shall never use.
