There is no act, however virtuous, for which ingenuity may not find some bad motive." -Thomas Jefferson
Not all criticims is bad
Criticism may not be agreeable, but it is necessary. It fulfills the same function as pain in the human body. It calls attention to the unhealthy state of things
Criticism vs Constructive Criticism
Criticism = this is bad
Constructive criticism = this is how you could have used the things under your control to make things better.
