Quick Tip: Present Tense
In the majority of my work, clients rarely tell me about their things in the present. I hear all about an object's past or the potential future it holds, but not so much in the present. When it comes to letting go of clutter, always live in the present.
What do you need now? What do you use now? What suits your current life now?
If it doesn't meet where you are currently. In this moment. Then it is OK to let go of it guilt free.
