Tell me what you’re trying to do.
That’s the question you have to be able to answer.
What are you trying to do?
If you can’t answer it, you’re not sure what you’re trying to do; that’s okay, break it down into smaller parts until you do know what you’re trying to do.
No need trying to do something you don’t know or understand – keep breaking it down until you do know, and then explain that simply and clearly.
