A palmist should not see palms of newly born child, violent, mad drunkard persons or those, who make fun of the knowledge of palmistry.
A palmist should be sensitive, sympathetic and a good psychiatrist. He should not tell about any unexpected event to the querent immediately.
Most people come to a palmist for wealth, marriage, career, position, education, children, diseases, litigation, ancestral property, disputes, illegal relations, love, love marriage, job, bad times, free reading, etc. related questions. So, one must concentrate on these topics only. Try to avoid very personal, secretive and sad matters.
Read palmistry literature as much as possible as it enhances the knowledge, experience and proficiency of the palmist.
