Criticism is a part and parcel of a successful life.

People who achieved extraordinary results in their lives, were
initially criticized or labelled as fools; because only they could
see their long-term outcome or vision. Fear of criticism is
one of the biggest obstacles in the path of success.
To be successful in this world I have to defeat this dreaded enemy -
fear of criticism.
Fear of failure is the surest way to failure.
Those who don’t do anything extraordinary in
life don’t attract any criticism. Criticism is a part and parcel of
a successful life.
No one has ‘learned’ from their birth. We learn through making
mistakes. How many times have you fallen down while learning
to walk? Please don’t get afraid to make a mistake just to avoid
criticism. Criticism is your feedback that you are going to be
an extraordinary person in the future. Coal had to go through
extreme temperature and pressure to become a diamond, and
this diamond still needs cutting and polishing before it can be
valuable. You are a rough diamond; dealing with criticism is
polishing the diamond that is you.
It is not what others do, but our own mistakes that hurt us the
most; it is our response to those provocations. What people say or do is under their control. But how you will react is under your control. You can have control on your thoughts, and thoughts are generated from your mind. Mind control is the result of self-discipline and habits. You either control your mind or it controls you. There is no half-way compromise.
What I realized the most practical of all methods for controlling the mind is the habit of keeping it busy with a definite purpose, backed by a definite plan with a definite time bound goal and by keeping my mind clean.
