After a degree in 1985, I worked till ‘92 as a scientist, in London and New York. I then did 18 years in heritage property for the Church of England, where I also wrote a national database and managed IT.
Age 45, I fancied self-employed coaching. So I trained as an instructor and find its benefits better than expected. I've written for industry magazines, and done well in my periodic Standards Checks (the DVSA's equivalent of OFSTED quality-inspection).
However, no teacher's perfect, so I even use my mistakes to help your learning.
See how I think my way works and, more important, students' comments.
