Except for shouting and showing me how I am dumb my Ph.D. supervisor not done anything. Always pushed me to work on his ideas on his timeline. Once I was not able to cope with the deadline supervisor threatened me that I will not be in this position anymore. This killed my complete motivation behind my Ph.D. and shouting-abuse killed my excitement about research. Just pushing days to complete the Ph.D. and crying in a toilet. Never thought of this day during Ph.D. :)
