I feel it is very difficult to manage time in research as it is non-ending job. As a researcher, one has number of responsibilities including time for self and family. It is not necessary that research output is proportional to the time you spend in research. I have seen numbers of researchers who work very hard, but their research output is not visible. Sometimes, we are so much involved in science that we forgot about our health. Health is another important issue, if you are tired you can not think much. I am asking this question to find out from other colleagues how they are managing their time. According to you, what is best way to manage time, in order to keep the balance of most of things in life? At end of day we have to live a happy life.
