Sometimes I think about how I should have worked harder and paid more attention to my courses while in university. My grades were pretty good (though could have been better), and I put effort into my projects and labs, but I feel that I didn't use my time well and didn't explore the opportunities, whether it was taking different courses, attending events, or finding like-minded people with whom I could have created something together, or even reading more books and studying a little more. After all, it was quite a short period of time, and after that, life just went downhill anyway.
