I would advise anyone interested in Occupational Therapy to read up on the profession or else try to meet a qualified Occupational Therapist and talk to them about their work.
The internet can be a great resource in getting information. Also information from the universities might indicate if this is a course that is suited to you. A lot of the course work relies on you being a self-directed learner. This makes the course different to other more mainstream/academic courses as the onus is on the student to complete a lot of work independently.
As this is a caring profession an interest in working with people is a must. You also need to be a good communicator as you will be working closely with clients, families and other staff on an ongoing basis.
Organisational skills are essential to enable you to manage a caseload.
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.
