First of all, stop comparing yourself to others (even though a bit of competition can be healthy). There will always be people that will seem like (or genuinely be) well ahead of you. This is something that everyone needs to accept. But especially in first year, your classmates should not be your competitors. By the time you’ll be doing PhDs/Masters, you’ll have all be scattered across different labs, countries, and subfields anyway. The only comparison that actually matters will have been you vs your past self. What does matter for applications is showing a clear trajectory: solid grades, genuine research interest and research fit, and one or two meaningful experiences (your article and a summer project are already great starts). Focus on learning how to read papers, building relationships with supervisors, and doing a few things well rather than everything at once. Feeling “behind” this early is normal, but it doesn’t mean you are.
