> make sure you're good at what you do and you won't have to worry about the market

No... make sure you strive to do the best you can in whatever you do. It's not about being "good enough". If you care about your work (whatever it may be), be a good human, and put in effort to learn and do the best you can at your given job - you will succeed.

Don't be afraid to take chances when you're young.

Being good at what you do is a side effect of caring about what you do and putting in the effort to learn about your job, your industry and the people around you.
