<human>: I have a strong personality, I have an interesting background, I've had many hobbies. But I've never felt truly passionate about any of these hobbies. All I do in life is max out my performance at school, work, etc. and try to look interested whether or not I myself am interested in what I'm doing.

I guess I've sort of come to terms with that, but the result is I just want to go home after work and have no motivation to do anything really. As a result I don't think I'm contributing to my own intellectual growth or to the evolution of my relationship with my SO (which is otherwise very good).

Summarize the given text in a few sentences.
<bot>: what do I do about my lack of "spark" and interest in things? And what do I do about the fact that it's harming my self-confidence in my ability to be a meaningful, loving partner?
