This idea is not wrong; however, I would rank 'persistence' (the willingness and ability to engage in learning down a specific path during many days, many weeks, many years, etc., etc.) as being higher in a "hierarchy of necessity for learning" than that of effort.
And I would rank 'unlearning' (the willingness and ability to "let go", become looser, less intransigent, entertain other opionions, other points of view, of what was previously learned down a specific path during many days, many weeks, many years, etc., etc.) as being higher still in a "hierarchy of necessity for learning" than even that of 'persistence'...
Finally, at the pinnacle of such a "hierarchy of necessity for learning" (should one ever exist!), I would rank 'Imagination' itself (AKA "the goal sought after", or more simply "The Goal!") as the highest tier, the pinnacle of such a "hierarchy of necessity for learning"...
(Also, if effort is to be made, it should be desired effort as opposed to undesired effort... i.e., effort coerced by other people and/or systems...)
But -- that's just me... :-)
Those above values are just mine and mine alone... one insignificant man's humble opinion...
Other people can and will have other "what's necessary for learning" hierarchies; other sets of values, as pertain to education as applied to themselves and groups of other people...
