If you want to make great photographs, start by having something you want to say to the world, something you want people to see, to notice, to remember. Once you have that in mind, you'll start seeing good subject matter.
I can't actually agree with this. I've seen multiple places where newbies are encouraged to find something "worth saying" and shoot that, but a newcomer to photography doesn't know what's worth saying. They will inevitably end up parroting someone else, since most of us learn photography by observing the work and process of others, and taking in lots of advice and instruction from established photographers.
I think the truth of the matter boils down to this: you won't know what YOU want to say for quite some time. So shoot anything and everything, and embrace the tough truth that you can't shortcut your way to being a meaningful or important photographer. Be an enthusiast, take snapshots, go with what moves you, and EVENTUALLY you will want to settle down to something that gives YOU a sense of meaning. That's your focus. That will be different for everyone but it's the only way to make sure that you start using your own voice, instead of someone else's.
