If a person reads a lot of theory about how to swim, different types of techniques, other people’s written experiences etc., can they swim if thrown in a deep swimming pool? Or, at least, be able to swim enough to reach the steep end and save themselves from drowning?
By “a lot”, I mean spending over 6 months to a year, gaining theoretical knowledge. And when we throw them in the pool, they are willing to try it, as in, “I have learnt enough, and I am willing to try it out.”
If they’ve read enough about the subject then they’ll realize that they’re not drowning. You don’t drown simply from being in water, the actions required to let you float with your face in the air is almost trivial. Knowing what those actions are is enough to get you to the “okay, now how do I go somewhere?” Step.
