I have a real problem when people write "I need to" followed by a description of what they "WANT" to do.

I would suggest that you restate the request as a business problem such as:

  1. I am doing such-and-such and it is too slow. or
  2. I am engaged in a pointless academic exercise. or
  3. ....

Because I take strong exception with the thought that you actually "NEED" to something in a specific way. Unless, of course, you are in a class and your instructor has made this a requirement and you want someone else to do your homework for you.
