Before, from when I was first thought about joining while I was in the air cadets to recently, combination of emotional and identity issues at the time got in the way which resulted in poor marks in High School, lack of experience, and so on. Then even with that resolved, it was a concern of legal issue and lack of CF seriousness/practice in 'equal opportunity' (in comparison to now). So I was convinced it would be pointless trying, despite success with other government funded organizations that I applied and participated/worked for like Katimavik. Even after getting to the point of it being a non-issue wherever I go and work for, as well getting the legal issues resolved, I was focus on moving to Montreal and starting University, which was another thing I previously thought I would never able to do. Once in Montreal, nearly half way into University, and achieving the goal of getting into a sport previously blocked by legal issues, it was only in the recent past month that I realized I have the opportunity to achieve another goal and interest previously blocked or considered not probable.
There was also the whole thing of being involved in anti-war, anti-globalization, feminist, and such groups, helping organize, marshal, and participate protests and marches. Overtime, I tone it down and limited to events I care about, as well to focus on other things in life. Even with the other interests and groups which I am still involved in, just seem huge contrast to even consider military. At one point I even considered applying for Ottawa Police, whom I have interesting relations with (go against officers during a protest one day, and then work with the police the next day about something else). Always had a balance, centrist, middle of the road views of life, world, and politics, providing an unique perspectives on things with whoever I am involved or work with. After moving to Montreal and leaving behind most of my friends, I felt freer, despite continued devil advocate type contrast within Poli Sci and Women's Studies (appear as leftist in one, and right in the other, interestingly enough). Also allowed me to drop off much of my activist commitments by moving, and in turn focus on school despite being part of one student organization and doing roller derby, both of which would be at odds, receiving lots of raised eyebrows at me applying for the military, which I would appear odd in as well.
At present, there is still some obstacles, yet they can be overcome, or simply made a non-issue. Physically I am already half way there, and I am sure can pull off the upper strength of PT requirements before summer. I have a couple bad marks in University from the first year due to essay screwups which can also pose a problem, but I plan to redo those two classes at some point later on while hoping third term marks increases my GPA despite some complications this past Fall. I require glasses/eye contacts, but are not huge factor considering some of the occupations I am interested in. -2.75 for one and -2.25 for the other, so not sure how that translates the 'vee' ranks. I manage quite well with eye contacts which I started wearing this past year for roller derby, yet understand there can be situations where contacts are impractical in the military. Then is the allergy to penicillin and that other thing I had to deal with long before that is now a non-issue which may pose problems in medical. In the reliability side, credit check can pose a problem due to recent financial situation derived from juggling school, work, and finding another cheaper place to live with unexpected complications, something I intend to have under control by January anyway, and caught up before summer.
So yes, about the only things I can think of being possible and most likely problems in my application.
