I note with interest that Cal, having chosen academia over a career in the "real world", seems to have become an expert in gaming academia in itself, its tests and admission hurdles, etc. There's nothing necessarily wrong with that; many people need a college degree for their own ends, and may be helped by what Cal provides. But navigation of the academe is not a large niche, not large enough to avoid making choices for. So the value of following the Cal's rule here is far from self-evident.
Making a choice doesn't usually preclude you from changing direction if you find, after investing your time and effort, that it's not working out. But delaying all choice is very rarely the right option. There's no good reason to think that time spent choosing will increase your feeling of certainty in what you choose.
When you come to a fork in the road, take it.
