Problem: Your blackout blinds that allow you to sleep until 4pm make your room look like a dungeon.
Solution: Lighting = ambience. Find a cool floor or table lamp preferably on a dimmer so you can control the light. Hint: Dim the lights to set the mood. I mean it is Valentines Day, right?
Also, one word of advice, avoid lava lamps and stick with something sleek and simple.
