One of the ways to insure that you are going to shoot a "keeper" is to spend some time with your subject. Shooting the thing from a number of different perspectives, angles, and exposures. This is true both with film and digital. Take more than one. Explore. Digital has a number of advantages using this approach. One of which is that it doesn't cost you anything (once you have made the initial camera purchase) to shoot a number of images. Whereas I might have been reluctant to shoot 8 or 10 frames of a particular subject with film, digital frees me up to play. This way, you might get a variety of images from the same subject that you will want to keep. Film makes this expensive, and makes you second-guess whether or not you should shoot something to begin with. Shooting alot will help make you a better photographer. After a point, your eye for composition, lighting (natural or otherwise), and color will improve to the point that the majority of your images are keepers.

The ability to preview your images, to sit down while still at the location and look over your images, is very helpful. Rather than having to wait until the film comes back to see what you shot, you can preview it immediately, and figure out if you have nailed it or not. Immediate feedback. You can critique what you are shooting on the spot, and continue to work with your subect until you feel you have it.
