I would advise them to get themselves physically fit and to maintain it. I would also say that a sense of humour is very important and the ability to laugh at themselves. They should have self discipline and be prepared to accept imposed discipline. Punctuality is very important as is respect for others. If they had sporting interests that would be a help.
Realists are usually interested in 'things' - such as buildings, mechanics, equipment, tools, electronics etc. Their primary focus is dealing with these - as in building, fixing, operating or designing them. Involvement in these areas leads to high manual skills, or a fine aptitude for practical design - as found in the various forms of engineering.
Realists like to find practical solutions to problems using tools, technology and skilled work. Realists usually prefer to be active in their work environment, often do most of their work alone, and enjoy taking decisive action with a minimum amount of discussion and paperwork.
"GMIT Open Day is a great day for both students and teachers. It gives students a taste of what college life is like, as well as an opportunity to get the information they need about particular programmes, to attend practical workshops, career clinics and finance clinics."
