For now, let's cover some of the basics including your entrance, your seat of power, your chef's station and your bed. Start at the entrance. Put a light at your door. For the most part, brighter is better. Lights are comparable in effect to miniature suns.
Lights are a positive force.
Also, hang a wind chime outside your door. Have the chimes make pleasant sounds to resonate with beautiful energy to channel into your place. Red flowers outside of the door tend to attract money. Outside gardens complete with rocks and sculpture are encouraged as is cultivating yourself. Inside the home, start to think of your desk chair as your seat of power.
