How can I spark up my interest and will to further in the university education?
I am writing this answer as someone who will soon be done with bachelor, and who will do everything that is possible to continue with masters and PhD later on.
To be honest, this wasn't my childhood dream. I wanted to become so many things, but my final choice was studying medicine and becoming a psychiatrist. Things went wrong. I failed the entrance exam and I started studying something totally different: translation.
In the university, I have realized that I am like working scientifically. I like writing papers or doing research. I like to argue with what people have written, and contribute, if I can. Moreover, I got some translation jobs, which I did with great effort, but it wasn't very much fun to be honest. I decided to go all the way with masters and PhD, and become a professor who gives courses.
I have many friends from my department who are not into working scientifically. They hate papers. I don't think it would make sense to have a masters degree; they need the certificate, and experience in translation.
It is important to see what you want first. Do you think having those degrees will serve you well? What do you want to do in the future? In other words, where do you see yourself?
If you think that masters and PhD are things that will help you reach your goal, then go for it. However, don't let them be your only goals. It is not a fun way; on the contrary, working hard and acquiring those degrees can be frustrating. It is better to know what lies ahead, and plan things carefully. If you don't want to do it, maybe letting go your childhood dreams can be a better idea.
Don't get me wrong, though. I am not saying it is better to quit. Just be sure it is the right thing to fight for. Once you are sure, the rest will come on its own.
