Choosing a career may be one of the hardest jobs you ever have, and it must be done with care. View a career as an opportunity to do something you love, not simply as a way to earn a living. Investing the time and effort to thoroughly explore your options can mean the difference between finding a stimulating and rewarding career and move from job to unsatisfying job in an attempt to find the right one. Work influences virtually every aspect of your life, from your choice of friends to where you live. Here are just a few of the factors to consider.

Deciding what matters most to you is essential to making the right decision. You may want to begin by assessing your likes, dislikes, strengths, and weaknesses. Think about the classes, hobbies, and surroundings that you find most appealing. Ask yourself questions, such as “Would you like to travel? Do you want to work with children? Are you more suited to solitary or co-operative work?” There are no right or wrong answers; only you know what is important to you. Determine which job features you require, which ones you would prefer, and which ones you cannot accept. Then rank them in order of importance to you.

The setting of the job is one factor to take into account. You may not want to sit at a desk all day. If not, there are diversity occupations – building inspector, supervisor, real estate agent – that involve a great deal of time away from the office. Geographical location may be a concern, and employment in some fields is concentrated in certain regions. Advertising job can generally be found only in large cities. On the other hand, many industries such as hospitality, law education, and retail sales are found in all regions of the country. If a high salary is important to you, do not judge a career by its starting wages. Many jobs, such as insurance sales, offers relatively low starting salaries; however, pay substantially increases along with your experience, additional training, promotions and commission.

Don’t rule out any occupation without learning more about it. Some industries evoke positive or negative associations. The traveling life of a flight attendant appears glamorous, while that of a plumber does not. Remember that many jobs are not what they appear to be at first, and may have merits or demerits that are less obvious. Flight attendants must work long, grueling hours without sleeps, whereas plumbers can be as highly paid as some doctors. Another point to consider is that as you get mature, you will likely to develop new interests and skills that may point the way to new opportunities. The choice you make today need not be your final one

     Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction. 

     Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta Texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. 

          The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space.  In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail

According to the passage, the highest amount of pheromone vapor is found _____
