Mr. Jacob has shared an excellent thought, and his reference to Dale Carnegie is very apt. In general, you can refer to any text on interpersonal relationships. You can also refer to other books like "7 Habits" by Stephen Covey, "Emotional Intelligence" by Daniel Goleman, "Motivation" by Richard Danny, and similar texts.
In addition to the above, also search in Cite HR by typing in your query in the search box and then pressing the Research button. You will get plenty of useful information.
