I Think Too Much

I'm at a loss.. I don't understand why, at all. One of the most popular and sought girls in my course of Robotic Engineering - of all the guys that already attempt to attain her attention - confesses that she likes me. Twice. I like her too, no doubt about it, but I am not dating her.
We both agreed we're not ready, which is true. She even apologised to me for liking me. But, for me more importantly.. why me? She works hard, she puts her natural talent for this field of work to good use and it will get her far. I neglect mine. She places me on equal footing as a academic, and I hate it because I feel like I'm failing her since I'm always one step behind her. I get depressed quickly, as well, I'm a lazy shit. I'm the definition of counter-productive and she is the definition of productive. I don't understand what's going on in my life.
