This is exactly what I have done, found my current job a bit volitile, combined with the fact I work away a lot!
I want a career change into the IT side of things. Something i have always been interested In. I found a place offering a good deal and enrolled in the A+,network+,Security+,CEH. They even give you bits of work experience along the way, help with your CV etc. I am really interested in cyber security/pen testing side. So I am hoping to get through all my exams this year and see where it takes me.
