No, not weird at all. PhD’s are pain, but certain people like the pain. If you’re good with handling stress, and also OK with working in a fast-paced, high-impact environment (for real, not business talk BS), then it may be the right decision for you. The biggest thing that I would say is that you should really, really think about whether this is what you want, since once you start a PhD, you’ve locked the next 6 years of your life into it with no chance of getting out
