Hi,
Congratulations on your decision to do a Ph.D. Like every other thing, Ph.D. studies also comes with numerous challenges. The challenges may vary depending on the type of research field. But the overall pros and cons remain the same. Long hours of work, along with no or nonexistent social life, is a part of the Ph.D. program. The prerequisites of a Ph.D. is patience; It is a virtue which is required in every step of your work, from enrolling into the program to getting your research paper published.

Positive virtues of the Ph.D. program can research your passion and find answers to questions, and it also helps to produce something fruitful to the community. It is really a feeling of a sense of achievement to see your name printed in research articles along with other stalwarts in your field.

Negative virtues include extended timelines for all your work. Sometimes things just don’t work out as you expect them to be, financially it is a huge burden: personally as well as professionally. There is an increased pressure to publish ‘n’ number of papers to establish yourself. Delay in establishing yourself with a well-paying job as your peers would be already earning and settled.

Having a great supervisor certainly helps to make your life as a Ph.D. student easier. If your supervisor is not great support, then even mundane tasks can seem overwhelming, but if he is excellent support, then the hardest of the issues can be solved without any hassle.
All the best! Choose your supervisor wisely.

Hi,
It is impressive that you want to pursue your dreams and want to get a doctorate. My suggestion would be for you to write to university professors whom you would like to work under, for your Ph.D. Discuss your situation with them and take suggestions . I am sure they will be able to guide you accordingly. It may even direct you to different opportunities which you were unaware of. All the best! for your future endeavors.

Hi, Quitting is an easy option. However, in the future, you may regret your hasty decision. I do understand your feelings. It is hard to get back to your thesis once you have mentally decided it is done. My suggestion would be to take it in a positive stride and work gradually. Do not overwhelm yourself with unrealistic deadlines. Try completing a chapter or a part of the thesis in a day (depending on the type of corrections required). Take adequate breaks and work towards addressing the corrections suggested by the examiner. I am sure you will complete it well in advance. Also, most importantly, before you start your corrections, take a day off from all your work, and just relax. I usually read a novel or watch a movie before I start studying for my exams. Do something which you enjoy doing. Recharge yourself with positive energy and get going. I am sure you will be able to submit your corrected thesis in time. All the Best!
