Everyone is engaged in such activities about which one’s heart continuously tells him that he was not at the right place. There are many people who lead their lives in this state and die in the same state. Nevertheless, there are some who succeed in emerging from this intellectual morass and take to the right path demanded by their nature.

Guarding the tongue means that a person should refrain from saying something offensive to others. He should protect himself, in all circumstances, from the evil that spreads in society. It is a fact that most social evils are spread through people losing control of their tongues. Controlling the tongue closes the door to all kinds of social evils. It is a sign of seriousness that a person should always use his language carefully. Misuse of language appears when a person harms others, speaks harshly to others, finds fault in others, and spreads rumors about others.

We should also consider that there are certain human beings who are known as "rough diamonds." That is, on the outside they appear to be unattractive and without merit, whereas on the inside they are of great worth. To bring out their worth, so that their true value is apparent to society, it is pointless scratching at the surface or using acid. If the upright human soul is to be revealed in all its beauty, it must be given the same delicate handling and treated with the same expertise as the master craftsman lavishes on a superb but fragile piece of jewelry.

Insincere behaviour is very easy to indulge in. One who is insincere is always ready to accede to the demands of the situation. You can easily understand what is in your interest and what is against it. In comparison sincerity is a difficult option. When you are a sincere person, you cannot afford to go against your conscience or moral norms. Sincerity invites you to ponder over the situation, to try to choose the best course of action, even if it is against your desires.

Someone who keeps a diary is known as a diarist. A diary is a collection of notes, kept in chronological order. Through a diary, one can thus keep the record of one’s daily intellectual journey. A diary can also serve as an effective means of self-introspection and accountability. By writing a diary, a person can continue to improve himself by knowing his successes and failures. Thus, a diary can become a source of one’s intellectual development.
