It's funny. I'm seeing this, while I'm thinking about dropping out of this career. I don't want to be one of those girl dropout stats, but lately I'm feeling a desire to start a family. fwiw I just passed 32 and I don't know if I want to do programming/software engineering jobs anymore. I'm hoping its just a phase.
Now I'm back in school in an unrelated field and realizing that coding can be an asset in the field. I'm working on a personal coding project as a way to get back into things.
My physics prof believes that going to school for computer science is like going to school to learn all how a shovel works, while other majors (like physics) just learn how to use the shovel in order to accomplish their goals.
I don't entirely agree with him, but it made me realize it was never coding that I stopped liking. It was coding about stuff I didn't care about that had killed my interest. (Interest in playing with technology for the sake of playing with technology had faded for me.) Now when I code, it is because the code is a step (one I find fun, enjoyable, and usually relaxing) towards another goal.
So, it might not be a phase. It must just be you are craving more.
