Right now, nothing, I already finished. Maybe in ten years or so, but I don't know what I'd do exactly tbh. I do like taking occasional workshops on various topics, just to update or refresh my knowledge a bit
I'm a junior and I still don't know. Whenever my counselor asks me what I want to major on, I always go like ''umm yeah thats still undecided''. And they look at me like I'm afraid I'll be in the same situation as you.
I hate the pressure and feeling like I have to decide on something now or forever be a failure.
