Rephrasing my question, how do I stay motivated in life?

I feel like suffocating the person who said life doesn't fails to excite me, I find my life like a constant cycle repeating itself. My day starts off like this waking up smoke before school to get rid of dread, taking the daunting transport, siting in class asking myself what the hell am I doing here and spending the whole day questioning or making sense of my purpose. I was interested in studying building once but after 2 years of that And obtaining a diploma the system post me to anoter course. I find it hard to accept it and remain motivated. What I once enjoy now seems dull.
