My advice: Do a PhD only if you're extremely interested in a research project.
I started doing my PhD since mid 2013 right after an MSc. This journey is due to end in January 2018. So near yet so far. This journey is lonely. It's very lonely.
I've seen some friends giving up of their projects after many years. I've also heard of other PhD researchers gave up of their PhD. For them, it's definitely a very tough decision to make. I understand.
"Trust me, PhD is much harder than working." - one of my supervisors.
The reasons why I took this project weren't strong enough, which is probably why I feel like giving up now.
I can't give up because it's so costly for my dad to fund me that I can never manage to pay him back. I can't give up because everyone is expecting something from me. I can't give up because it will affect my supervisors' reputations and they will also have to bear the consequences. I can't give up because I don't want to.
But, my brain is so stuck.
Maybe most of the PhD researchers can understand my feelings. Writing up seems to be so much harder than I expected. I used to write very quickly, but now I am just so stuck.
I don't blame anyone, but myself. Sigh.
