What do you think of who is behind with their studies?? Like have you ever had friends or colleagues struggling and taking longer that normal?? I had problem with my studies because of dyslexia and I’m older than anyone else also depression and these kind of fields are so competitive and I feel always judged and hopeless and just old and with no real possibilities…. congratulations on your phd :))
Let me tell ya, I know many people who didn’t complete their studies within the ‘normal’ amount of years. In physics, I would say those who did were a minority. I myself finished my studies two years later than I was supposed to. Still got into a PhD. It’s true, it’s an insanely competitive field and it’s never easy. But I think you have to keep in mind that the science world is a bit different than undergrad/graduate courses, being older doesn’t really matter. What matters is the quality of your work. And comparing yourself to others won’t be very helpful to you. I lost one year due to depression, another to laziness and procrastination (and self doubt, and all of that). I think what got me through is what my high school math teacher once said to me: “the drop will dig into the rock”. Do all you can, but do it. Best of luck!
