Our mind always keeps running in the past and future rather than living in the present. Though life is all about being in the present moments. But how do we distract our mind from these disturbances? 
Sometimes silence is that tool which helps you learn, explore & express. Utilize it for self improvement. When words fail...silence speaks a lot. 
You are the creator of your own life. It depends on you which colours you want to fill in your life. So live a life full of moments and happiness.
