I had always wanted to be in a uniformed service of some sort, first preference as a fireman, then the armed services or the police but I have an eye condition that rules me out of these jobs.

So during school I had no idea what I wanted to do and I was not the most academic of people so I chose the subjects that I was better at and would stand me the best chance of good grades.

I did not really choose to follow this career path until I was 25.  I had been to university once to do a Coaching Science degree as I was heavily involved in swimming and water polo coaching but this just did not suit me and I dropped out in my first year. So going back a second time as a mature student was a big decision and because I was a mature student they look at you a little differently to entry requirement and take into consideration life experience.

So at the time it was having maths and english plus experience working in sports coaching groups that I think were the main factors. Even the fact that the course had a lot of geography and I had dropped this subject when I was 14 or so, did not go against me and the first year of the course is there to get yourself acquainted with the subject again. 

So in hindsight I was lucky enough that my subject choices in school did not affect my current career.
