Whatever your outdoor lighting needs, planning and plotting out a scheme are necessary. After you've done that, your next step is choosing the lights you'll need and installing them. It may sound like a lot of work, but the result will be pleasing to the eye as well as the psyche. In the evening. So you want to enjoy your garden in the evening as well.
Outdoor lighting is the best way to do that.
Usually a large tree, landscaped island, main entrance, or even pathway provide the most outstanding focal point. You may choose more than one focus, but any more that two probably will simply dilute the effect. At night, see if there any dark spots around your home that may be a security risk. Corners and building-hugging bushes are common problem areas. Check if obstacles such as steps are clearly visible.
