If you like working with others, and like problem solving then its definitely worth considering. Do you ever look at a bridge/skyscraper etc. and wonder how they did that? Or better still, are you looking at the way the road at home is laid out and thinking if they had of done something differently it would have been better.
Engineering is not a career people think about and say its helping people, but in many ways it is rewarding and just as much about helping people. Engineers design things used everyday that help people get to work, provide clean water, provide sewerage systems, care for the environment....
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.
