Lighting is a key Feng Shui technique for enhancing the energy in a space. Beautiful lighting makes you feel good, and feel good about the space in you are in, so it's a great way to motivate yourself to organize and keep things neat!
For example, if you have an area that you tend to be messy with, cast a spotlight or uplight on it! That is a sure way to make you want to keep it neat. Once you've organized the items on a shelving unit, for example, lighting up the inside of the unit will make it a feature you will enjoy looking at, and you know visitors will notice, so you will make an extra effort to keep the shelves neat!
All the best,
