Please remember to capitalise the first word of every sentence and to end every sentence with the relevant punctuation mark.
"Thanx" is not a correct English word. Please use "Thanks".
Did you look up "worth" and "worthless" in a dictionary? What don't you understand about their definitions?
We like to help when we can, swety, but there is little point in our trying to do what many dictionaries here already do very well. If you have problems with the definitions or example sentences you find in those dictionaries, post your specific problems here and we'll see what we can do to help.
