An IT professional tends to already have an interest in IT an computers. They tend to be expected to do a lot of learning outside of work and so need to be prepared to put a lot of hours in. There tends to be an association with IT professional and being nerdy or geeky, but this is unfounded. They are not all like this, but they do tend to have a love of all things technical. Therefore if you like IT and have a willingness to learn, then doing a job in IT should suit you.
