Secret for doing a PhD: Motivation

Today was really strange. Though I already found some interesting stuff and wrote some papers/drafts, I woke up very worried about my PhD progress, specially when thinking about how much more is needed to have a whole thesis. So after some initial hesitation, I decided to go to the lab and try to work a bit to fill out the gaps needed to finish my work. First thing I did, after arriving at the lab, was to go to my supervisor's office and discuss some issues that I found interesting and just after some minutes my mood was completely different: I was excited again! Motivation was definitely the necessary ingredient for changing my mood from completely desperate to full of hope!
