With regard to education I say don't worry if you think you have the wrong subjects in school. I certainly didn't have the subjects you would typically expect.
There are a number of courses that cater to different backgrounds. The most important thing is to do your research. Go to open days, talk to the colleges and generally just find out what exactly you would be getting in to.
Don't just take for granted you know what a certain course or career is all about. Think about what you like to do, and not just necessarily in school, if you find yourself being curious about how things work or how thing are made, it's a good indication that you could like something like engineering.
One of the best things about engineering is that it really can be your passport to the world. There are great travel opportunities within the industry and chances to be involved in the next big thing.
Practically every man-made product around you came from a manufacturing plant, it's a huge industry with a lot of different avenues to take. Innovation is a really big part of what engineers do. The desire to be creative and improve production and processes is an important attribute for a manufacturing engineer.
The Social person's interests focus on some aspect of those people in their environment. In all cases the social person enjoys the personal contact of other people in preference to the impersonal dealings with things, data and ideas found in other groups.
Many will seek out positions where there is direct contact with the public in some advisory role, whether a receptionist or a counsellor. Social people are motivated by an interest in different types of people, and like diversity in their work environments. Many are drawn towards careers in the caring professions and social welfare area, whilst others prefer teaching and other 'informing' roles.
