How often do you consume DS content outside of work?

I'm just getting into DS (I'm interning atm) and I find it incredible how other MLE or DS have so much knowledge about this field.

Should I read books like "An introduction to statistical learning" and "Probabilistic Machine Learning" outside of work? Or should I only read specific topics when I encounter a problem at work?

Is there something else I should be doing outside work like online courses?

Impostor syndrome is real y'all...
