Confused about how to organize variables.

gistfile1.rb

class Todo

  def initialize item
    #what we need for a new item on the todo list.
      #when the item was created.(optional)
      @time_created = Time.now
      #the string that is displayed that's identified.
      @item = item
      #whether it's done or not
      @done = false
  end #of initialize method.

end #end of todo class.
