It Pays to Be Honest

Nowadays, many people choose not to be honest in our modern society. We almost can find such things every day of our life: some students cheat in the exam for higher marks; some corporations tell wrong data to the public in order to get more investment; and some doctors treat their patients with unnecessary and expensive medicines in order to make money, sometimes damaged the patients' health, even their life.

Seeing this situation. I think it must be changed. Being honest will benefit not only others, but also ourselves. First, your honesty will make others willing to trust you. Second, being honest can lead you to face your problem bravely, which helps to solve it. And the last, honest surely helps to make the society more harmony.

So. I think everyone should start to be honest and everyone should have the idea that our society can not do without honesty.
