Never tear down anything unless you are prepared to build something better in its place.

This rule applies to both individuals and things. It’s easy to criticize
other people thoughtlessly for their shortcomings, and equally easy to find
fault in their work or in situations that are not to your liking. It is far
more difficult to be a builder of people and to create works of art, useful
products, or profitable businesses. Make sure you are a builder, not a
destroyer of people and things. When you criticize the actions or work of
others — your children, your employees, or others for whom you are responsible
— make sure your criticisms are positive and directed at the act, or the
opportunity for improvement, not the individual. Include specific suggestions for
their application and focus on the potential for success.
