i think we have only two kinds of human being here on earth... and that is stupid and clever... it is true you know... because everything human do or think or say can be justified with this two words....

so for example, if you are lazy to go to class, then you are stupid because you dont think about the consequences.... of coz in the sense of academic, you'll lose some valuable lessons and knowledge and so you'll have trouble when you sit for the exam and when the result is out you'll fail and so the word stupid will come in mind.. and if you are rich and you like to donate to those who really need the money then you are clever becoz not only you do charity, but you also help those people from suffering and thus made the earth a better place...

and if you are a genius and you have the power to change the world but you tend to use that power to destroy it, then you still are a stupid person coz you cannot use your genius brain to do some good... and if you are a not so brilliant person and then you also make the world a living hell then you are a total idiot times 100 becoz not only you yourself are stupid, but you also make others life miserable... so still you are stupid...

and a clever way to live is to be a clever person... clever person means you can think and you can use that thought to ease your own living and to ease other humans' life... you can either do things or you can do nothing... by choosing the right thing to do or not to do you'll become a clever person...

so... humans are either stupid or clever... nothing more...
