Hi, I have the following problem probably you can give me some comments because of your experience. When I start a job in physics and I think that the task is not related to my present knowledge so I worry too much. Previously I got a postdoc and I was under pressure almost all the time. I start thinking about the duration of the project (which is commonly for one year) and I think that maybe after one year my contract wouldnt be renewed and several other things more. I really like doing research I mean reading scientific papers, looking for information, developing mathematics, learning. I also like teaching. But my problem is that I am thinking always about the time and the number of papers I should publish. Most of the time when I receive a new project I get stressed because I think that I wouldnt be able to perform the tasks. I think I wouldnt have these thoughts if I didnt have the time and publications factors present. One of the things I think is what would happen if my contract is not renewed, where would I go? I wanted to ask you if you have been in a similar situation before and if you have some comments, Regards.
