Perhaps overly impersonal, but I think of it as an investment profile: you need diversity.

Invest in your education, invest in your career, invest in your family, invest in your friends, invest in your hobbies, invest in your health.

Not all of those are sure to succeed, but if one fails or you realize is overvalued, you've still got a lot left.

I have two comments.

You want you career path to follow; what you can learn, what you can do, what you know, who you know.

Every job should pay you in, experience, money and connections. If a employer is short changing you or blocking you on any of those, LEAVE.
