It takes time and ammo. Lots of ammo. But the more (high quality) help you get along the way the faster you're likely to progress.
Its hard to know exactly what you most need to work on, not knowing where you are now. And we need to understand what your present goals are. Do you want tight groups? Or are you going for ultimate "combat accurate" speed at contact or "bad-breath" distance as might be most useful in a real shooting?
I would always say to start by learning the fundamentals of marksmanship -- good sight picture, mastery of trigger control -- and for that you need to be using your sights. Best point shooting technique comes after many MANY thousands of rounds getting the feel of the gun into your hands. P.S. is (at its best) a series of shortcuts that work because your body is already trained to do the right thing, so that when you shoot with great haste at short distance you can rush over the last details of the sight picture (or not even see the sights at all) and not blow the shot.
My "perfect world" solution would be for you to find the closest IDPA club to you and go shoot with them on their practice nights. IDPA may not be a lot of things that high-speed-low-drag operators care about, but it is a great way to learn practical accuracy and real-world gunhandling skills. And the folks who do this are generally very generous with their advice and guidance, if you ask for it with the manners of a student, and you show them that you are safe above all else.
On a more specific note to your question: At the very least I'd pick something like the FAST drill and practice it over and over again. Concentrate on what you do that gets you the hits you want. Bad practice is worse than useless. Only good practice makes you better, so practice drawing, aiming, and firing taking the time you need to get your hits. It may seem like forever, but a miss doesn't count. I'd stick with one drill for now because that's the quickest way for you to see results -- and seeing improvements will be a boost to your efforts to continue practicing. If you do a little of this and a little of that you really won't be able to track progress at anything and it will feel like you're spinning your wheels.
Practice until you think you're getting sloppy, then pack it up and try again next time. Tossing rounds down range just to pull the trigger is wasting time and ammo.
There's SO much more to say, but without standing on the range watching you shoot it's hard to be more helpful.
Good luck!
