Psychology is a very broad area and I would encourage people to reflect on the field that would suit them best. If you study pharmacy, you will graduate as a pharmacist. It is different in psychology. The role of a Clinical Psychologist differs significantly from the role of an Educational Psychologist, a Forensic Psychologist or a Sports Psychologist. A post graduate qualification will be required to practice in any of these fields.
Regardless of the area of psychology that interests you, respect for and an interest in people is a key value that is required.
Once you have qualifications, networks and professional bodies are a good way to meet prospective employers.
Not surprisingly, some aspect of the natural sciences will run through the Naturalists interests - from ecological awareness to nutrition and health. People with an interest in horticulture, land usage and farming (including fish) are Naturalists.
Some Naturalists focus on animals rather than plants, and may enjoy working with, training, caring for, or simply herding them. Other Naturalists will prefer working with the end result of nature's produce - the food produced from plants and animals. Naturalists like solving problems with solutions that show some sensitivity to the environmental impact of what they do. They like to see practical results, and prefer action to talking and discussing.
