I read the article more as: take the leap, but recognise when to step back reassess.

A good thing to ask is why you dream about a particular thing so much. is it even your own dream? or something society has told you to believe in? why so much dissatisfaction in the first place that you have to go crazy chasing something.

Myself I've never had any real difficulties when dreaming things.

This assumes that your dreams are internally consistent and that you have defined them well enough to know when you’ve achieved them. I’ve met very few people whose dreams that satisfied both of those criteria. If you are one of them, my anecdata marks you as the exception

No disagreeing. It's worth reading up on what people regret when they reach end of life. It's hard to predict future fulfillment, and I bet that living a well-rounded socially-minded life would go further than "grind for the dream"
