Structuring an argument

I can never quite find the proper arguments for my essays. I always seem to search clumsily around them, always mentioning things that are related to them, and almost good arguments, but always lacking key bits of information. If I do find an alright argument, though, I’ve usually misunderstood the essay question. Again, this probably relates back to structuring and planning. If I structure and plan my essays, I probably won’t have these problems. Well, maybe the reason for the arguments is that I don’t have the time to find them, who knows? I should really start doing my work sooner.
