I think it's often the information holder that opens the door of opportunity for us. One of my colleagues used to be the one who processed all paperwork/announcements in my school. Most teachers in his position would emphasize announcements from the government and disregard those from the private sector. They are supposed to put everything online but you know how bureaucrats work and sometimes they just have to be selective. My colleague saw this flyer for a competition hosted by Cambridge Press and thought I might have a chance. He personally delivered the document and brought it to my attention. I got lucky and won the competition and that turned out to be the start of a string of opportunities. I was recruited to a local teacher PD group afterward. I also won another competition hosted by OUP a few years later. I guess it's like a good start of everything. People started to know me and I was invited to give presentations, not to mention that I began to feel more confident and secure in my place at the school.
I wouldn't have noticed that announcement if it hadn't been for him and I've since asked a lot of teachers who work at public schools just like me if they heard about the contest. None of them had.
