A typical day for me includes trying to wake up early as much as possible to start studying. I designate some goals to achieve per week or per day. After achieving my goals, I reward myself by watching a movie, going somewhere or shopping. Balance is important and I achieve this by promising not to study after achieving my goals and trying do some exercise after finishing my studies. It is important to relax to keep going forward. A PhD is a long journey and stamina is crucial.
Studying for a PhD is the most difficult task I have ever started. It's more demanding, more tumultuous and more volatile, but it's also more rewarding. If a person passes this barrier, the academic world will be wide open.
