Recently I noticed that whenever I have presentations to give, I end up spending quite a lot of time preparing for them. I imagine perfecting presentations takes time for everybody. But probably I take more time the average. As a result of the preparations, my presentations are well done, however, the issue is that while I am preparing for presentations, I am not actively doing research. Therefore, in that period of time, my research slows down a little. This is especially the case when I have very important presentations to give, such as at an international conference or for a job interview. At such times, I end up having a clear break from the research.
I understand that communication is an integral part of the research. It obviously has many benefits. I am not looking for ways to avoid/decrease communication, but merely expressing concern, and would like to know how fellow academics find the balance between spending time on research and preparing for presentations.
Some advice on this topic would be very helpful.
