I paid for it with my 20s and my 30s. There was a lot of stress that I had to deal with back then.
Doing research is stressful, as is trying to publish one's findings. When I began teaching, I thought that my stage fright would disappear as I gain experience. It has been well over 10 years now, and I still find public speaking to be stressful. Perhaps I will feel better in another 10 years. When I was a high school student, I hated having to do class presentations, and having to write essays. One time I even got my family doctor to prescribe Ativan to sedate me before an important presentation. Now my job is to write research papers and to do presentations... Having said that, I am not complaining.
It's funny I would not guess that you are a teacher !
More like a solitary wolf, no offense !
And with your Tinnitus, does it bother you as a teacher ?
