There are two types of people in the world．Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy．This is because of the different ways in which they consider things, persons, events and the resulting effects upon their minds．
People who are to be happy pay their attention to the good side of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather．They enjoy all the cheerful things．Those who are to be unhappy think and speak only of the opposite things．Therefore, they are continually dissatisfied．By their remarks, they sour the pleasure of society, hurt many people, and make themselves disagreeable everywhere．The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes．I hope this little warning may help them change this habit．
Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck．Nobody loves them, and no one treats them with more than the most common politeness and respect.This frequently puts them in bad temper and draws them into arguments．they should change their bad habits .If they do not, it will be good for others to avoid any contact with them．Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels．
