Exercising and Training the Tongue
This task requires training and exercise. However, it should be a deliberate and persistent training, not one that the person focuses on due to emotional stimulations for a short period and puts it aside afterward; it would not be fruitful in this manner. People who are studying in college, if they persevere in studying for a short period, but then lose steam, will not reach the desired outcome. Only those who are sincere and unflinching in their education and training will succeed.
