It is not so much that traditional networking is obsolete, but rather that your digital presence now serves as the permanent record that reinforces those face-to-face connections. I would suggest viewing your online portfolio as a low-maintenance multiplier for your career rather than a replacement for campus life, since building a strong footprint allows you to showcase your side investments and projects to people you might never meet in person. Since you are already feeling spread thin, try picking just one platform like LinkedIn or GitHub to document your progress rather than trying to build a brand everywhere at once. Quality connections formed in class are still irreplaceable for mentorship, so treat your online presence as a way to stay visible to those classmates and professors long after the semester ends. Prioritizing your well-being and grooming, like getting that haircut, is also part of maintaining the professional image that supports both your physical and digital networking efforts.
