It will give you mental peace. I think honesty is the best policy because being honest will give you mental peace. You don't have to live with guilt because you lied. If you are always honest with people you don't have to remember the lie you told them. The other person will always trust you. Being honest with someone shows character and shows that you trust them enough to let them know that you tell the truth and nothing but the truth. When someone feels you are honest with them they tend to trust you more and this builds a strong relationship. It also assures the other person that you are trustworthy. Dishonest people don't get second chances when they lie because people are going to think they are always lying to them.
