What we think ?

Think , what we think , is not question, Question is how we think,Think is nothing but the related relations of other thing.Sometimes We feel something i am thinking but i can't identify it what i am thinking.Why? "Think " comes from what we are working or completing in everytime .
from this done thing, something is working in our brain but we don't know , we tried but we become angry coz we fail to make it true .So sometimes we called it "Tension" .

In physics what is tension ? It is the maner of matter how muc it hard before it break or torn.
so when we think with various thing & we don't know how many thinkings we are thinking is called tension.it happens coz if we are unhappy in various sector social , economical, friendship, conjugal life etc .So it's nothing .We all know everything is a part of life but we don't agree mentally .But we know also that it is true that life is not much smoother.It is very difficult & polytechnical circle ,the man who can maintain this circle is success.

Tension & Frustration comes from various thing & from some part of life if our time is not properly used before .But how we know we are using our time properly ?

Yes sometimes we don't know & sometimes we know. Part of life when we don't know the proper use of time
