It's time to quit the demolition crew and join the construction crew

I have seen people with noble visions having their visions crushed
by critics.

There are two modes of criticism. There is one which crushes to earth
without mercy and another mode which believes that no vision is
entirely in vain and so scrutinises circumstances, motive and objective
before it criticises and then help with advice.  The first kind of criticism
demolishes and the other helps to construct. For most of us the first kind
of criticism comes more easily. It takes little thought, less effort and even
less wisdom to kill with criticism. The demolition critics are interested in
making themselves look good by making others look bad, they talk much
and do absolutely nothing to help. When we find ourselves encountering
this demolition criticism from ourselves or others our best defense is to
try to ignore it and take it as an article of faith that even though we make
mistakes we are great because at least we dared to try.
The second kind of criticism which is thoughtful and careful coming from
ourselves and others is invaluable because it actually recognises and
encourages the worth of the efforts we are making, even as it points out
how we might grow differently.

Years ago Theodore Roosevelt said this about critics, "It is not the critic who
counts, not the man who points out how the strong man stumbled or where
the doer of deeds could have done them better. The credit belongs to the man
who is actually in the arena, whose face is marred with dust and sweat and
blood, and who if he fails, at least fails while daring greatly, so that his place
shall never be with those cold and timid souls who know neither victory no
defeat."

Visionaries when you get pelted by unfair criticisms as you stand for your
vision just remember what Theodore Roosevelt said back then.
To all critics I say it's time to quit the demolition team and join the
construction crew.
