I think to enjoy learning, you need to cast the net wide and
make a paradigm shift. Essentially we tend to compartmentalise
knowledge. BY not compartmentalising what you NEED to know, you
open your mind to peripheral areas which CAN lead you back into
what you need to know. And this time, when you look at it again,
you look at it with a different perspective.
i.e. Maths is boring. However, YOu like literature or history or
nature. So, you look at some life stories of mathematicians (and be
amazed that it can be so interesting), you read about how certain
mathematics theorem can be applied to nature, i.e. symmetry ratio
in flowers and plants etc.. how maths are used in code that are
used in wars...read abt the impact of maths on people.
OR you might love MATHS and find literature and history boring...
then you draw relationships, compare, analyse, why does this action
equal to this reaction? What equation happened, that resulted in
this answer?
Essentially, all knowledge is linked. The greatest scientist is an
artist who creates new things, and in the art of a great artist is
a mind who can perceive detail, translate the intangible into
tangible.
