Mental floss takes work and requires more attentiveness than dental flossing my teeth. I need to mentally floss out the junk that plagues my brain. To loosen up the grime that halts my positive thinking in life. I use mental floss to clean my brain's crevices and roots. My roots are thoughts that perpetuate into conceptual memories that trigger my reactions. Mental floss is something I routinely do on a daily basis. I polish my brain until I feel like it is ready enough to help me shine brilliantly.
