The first people to criticize the efforts of others, often times end up being the ones that do nothing themselves. Solving a problem takes the efforts of many to see the problem and begin to find constructive solutions. It only takes a few to criticize and undermine the efforts of many. Try to be the kind of person that looks at problems from all sides, and offers solutions and help to get the job done. Constructive productive ideas produce solutions. Negative destructive criticism will poison good people and in the end hurt all those around them.
