Definitely agree with some of that. Telling people who "don't know otherwise better" to do most anything is dangerous, let alone something as extraordinary as changing their career.

My point is: For many, the most dangerous attitude to have about a so-called "steady" pay check is that it will remain steady, and that they'll remain engaged in their work for years.

For many people, especially those early in their career, the biggest risk of all is to not try new jobs, roles and challenges. Basically, becoming prematurely specialized.

Startups, especially, are great at solving that risk, and thus lowering career risk overall.
