A question relating to research papers (couldn't find an appropriate label) I have seen at least one research paper mentioned in many of the people's profiles. Doesn't it get very hectic when you are writing a research paper and also trying to maintain a decent GPA? Like a proper research requires a lot of dedicated time to result into something significant. I want to write a paper too to strengthen my profile but am afraid that won't be able to find time for it. Am I overthinking about it?
