What personality do I need?

Personally, you should enjoy working with people and should know how to think "outside the box". You should be prepared to work long and irregular hours in order to work client orientated. You should be prepared to work within an inter-professional team. A healthy lifestyle is also important.

Ultimately, you require the subject choices and performance in school to qualify for acceptance to university. You can contact the universities of your preference to acquire these standards.
