Good luck buddy, I remember when I was stuck being a security officer and doing all shifts and hours under the sun, moved around all the time in different jobs from factories, offices, shops to building sites, Edinburgh, Glasgow, Aberdeen, Dundee and as far away as Wick.
Then I had a chance of getting a permanent position security-wise in a building in Edinburgh that had companies which were banks, solicitors etc but it was a permanent position so I took it, 12-hour shift work which included weekends but I was happy with that.
I plodded along for 4 years and then I was made a security supervisor in that building and then a position came up in the company that were the landlords of the building as a supervisor with them so I took that position, from there I worked my way up from being security building supervisor to management running the security and building in general.
Bit of a rant there but it goes to show you in life if you get stuck into anything you can achieve something in life so I reckon you have a chance by the sound of it in doing the same, best of luck and I hope you go far in the job.
