I don't believe the average person lacks focus. I believe people tend to focus on things that may not be meant for them.

Many people have trouble "finding" their focus, not actually focusing.

Like I said, context.

Someone could take that one word answer (I haven't read the edit to this post yet) and say okay, I just need to stay focused on what I want.

Not really.

Also you may be throwing dedication into your definition of focus, which again proves why it's a silly question. One word alone doesn't do the intent any justice.
