Take interest in your studies while at the university. There may be times when you do not know what your interests are. If that is the case, it is actually an opportunity. By keeping a broad outlook, you may be able to narrow down your interests and study them to great depths. In order to do this, it is first necessary to rid yourselves of notions of your strengths and weaknesses. Attend all classes without bias, and always ask questions while honestly taking in the ideas from the lecture. Everyone gets irritated and impatient when they cannot keep up with lectures, but take it easy and ask your question a week later. Ask a question that includes a bit of confirmation, like "I understood this point in this way. Is this correct? But I’m not sure about the part that follows...” By doing so, you will find your own ideas and take interest in your studies.
