Ph.D. is not all that tough. I mean, it is tough but not nearly as much as people think. Well, I did it, and I am still alive and healthy – and happy. In fact happier than many. Now, I had a passion for literature, and that was my motivation behind opting to go for a Ph.D. The fact that I was good at research also worked in my favor. However, if you are not so good at research, you can still go for a Ph.D. What people find the toughest is the Ph.D thesis, and I don't argue that. However, that's still not a valid excuse because there are websites that offer Phd Thesis Writing Service and they are pretty good at that. If you really want to go for a Ph.D., you will find a way. If not, you will find an excuse. And, “Ph.D. is tough” is one of the most common excuses.
