One of Buddha's steps on the eightfold to relieve suffering and end desire is the right mindfulness. This means that you should be aware of what your body is doing and also what your mind is thinking about. The way that this helps to remove suffering and desire to have things is that you should resist the times when you find an object and it brings back memories that make you want to keep the object. That is one of the steps, hope it helps!
