If you can’t think of an alternative to your criticism, wait.
Don’t make the criticism,
because it is futile.
If you say that this medicine is not right,
maybe you are right,
but then where is the right medicine?
Criticism never brings revolution.
Criticism is good as part of a positive program.
So first decide about the positive program and then,
keeping an eye on the positive program, criticize.
Then your criticism will be very valuable,
appreciated even,
by those whom you are criticizing.
Nobody will feel offended by it,
because while you are criticizing,
you are continuously keeping
some positive alternative in mind and
then proposing something.
