All of your examples can be good goals. But a purpose is more important than a goal. What do you expect after achieving the goal? For your career, just reading X books or learning technology X is not enough. You need to show your skills in a job interview. If you want to prepare a job interview or a resume, what you need to do will be more clear. For your current work, improving products looks like a good goal. But how about learning and sharing knowledge to your colleagues? You can create a internal project and open to the public. Lastly, if you are happy while you're exploring somewhere not related to both your current job and your future job, it could be a good goal for you. It may also help your career in a long term.

But at that time, we'll be fired ;)
