The reason was that I was able to write and able to make a good argument. I knew how to write. At least, I had that skill. Ordinarily, there were people who sometimes made decisions that went against me, but when I presented my arguments, my report was a lot better. That helped me.
I always fought, and I always won, although a lot of others were not able to stay. To pass the test, I had help from a lieutenant. He helped me, him too, because he was kept in a lieutenant position for nine years. He was working in the same situation as me, and the path was also blocked for him. However, he had time to do a doctorate in administration over those nine years.
We worked together. He was the one who submitted my case, because he was an officer, while I was a corporal. I did the writing, and he submitted my cases. He was the one who told me that I had fought a good fight, but there were other people who would find themselves in my situation. He told me that I might be a good guide for those people, since I knew how to write and compose complaints.
I also worked on that skill, which was latent, over time. I was a warrior with a pen. I have continued to write. It is what I have done all my life. I have fought to keep my place.
