If it is possible to get some work experience during the summer holidays or weekends, it would be great. Find out if there are any positions (voluntary or otherwise) available in your local IT or University. Get involved in a hobby such as model making, this would be very helpful as it would help with dexterity & impart an understanding of the ways in which different materials interact when assembled together.
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.
