It's a great achievement to be successful,
Not being successful is always painful.
Success brings name, fame and glory,
Failure pushes us to the state of misery.
How can we distinguish success and failure?
We may have thousands of definitions, I am very sure.
Both are the two states of mind,
May leave a strong impression behind.
I don't agree with the word 'Failure' as the opposite of successful,
It should be 'unsuccessful' to make it more meaningful.
A completely negetive and deliberate state is failure,
'Not successful' is partially negetive and requires some care.
Failure is the result of not making an attempt,
Unsuccessful is when one fails to succeed after all possible effort (s).
