You do need a shitload of practice, but it has to be the right kind of practice.
If you just draw the same things over and over without learning, you stagnate, because you're just repeating the same mistakes over and over.
You need to learn about perspective, lines of motion, hues balance, colors, how certain lines are used for which situation, anatomy, proportion, etc.
Your best bet is to start drawing simple objects: cubes, spheres, prisms, cones, etc., from different perspectives, with different illuminations and so on, until you get those down path (since those are the basic shapes that make up 3D objects), and then work on textures (wood, fabrics, hair, rock, metals, glass, plastics, etc.), then combine all the things learned until you can convincingly, say, draw a metal sphere, or a wooden box, and so on.
I'm a little iffy on the order here, but basically:
Then you move on to slightly more complex objects (think 'still lives'). Then backgrounds. Plants. Buildings. Mountains. Rocks. Gardens. Then things that actually move, like animals and humans. You need to learn anatomy for both.
Somewhere in-between you keep applying what you learn of color and motion and so on.
You basically need to work your way up. Some people can like, instinctively grasp complex stuff (which is innate talent), but that doesn't mean that you can't learn, even if you're old. You just have to play catch up until you learn those lessons and make them instinct too.
If it's something you really want, then don't give up.
