In most cases it's mislabelling. Most people want FI and get saddled with RE.
The ones that claim to want RE need to figure out two things:
a. Their raison d'etre.
b. What will they do with their time?
Chasing FI is important but not critical. It just gives you more degrees of freedom in making life and career choices. The earlier you achieve FI the better, but there's no need to aim to hit it when you are 35 or 40. 55 / 60 is good enough given that life spans now are well into the late 70s early 80s.
RE is subjective. Most passions are passing fads and a whole lot of people don't know what to do with their time.
In summary, to give a cricket analogy - just like a good test match batting innings, people should learn to pace their lives. Everyone cannot be looking through a T20 innings lens to finish fast and finish big.
