Mouth...
Life is like a mouth.
The morning breathe is hardly fresh, even if you brushed the day before, you need to brush again today.
To stay fresh, make learning a dutiful routine.
No matter how nice a meal was, if it lodged particles in our tooth, we pick them out. This teaches us to deal with issues in our relationships no matter how sweet it is going, because the particles we fail to pick now, decay the tooth later.
Bad Breathe also turns people away, the same way failure is an orphan. So don't cover or ignore your weakness, confront it and keep looking till you find a solution.
Maintain, Remove and Refresh Daily... because Life is like a mouth.
