Summary
Mind
mapping
—
an
effective
way
A
mind
map
(or
mind-map)
is
a
diagram
used
to
represent
and
organize
words
and
ideas
linked
to
each
other.
It
is
used
to
generate,
visualize,
structure
and
classify
ideas,
and
as
an
aid
in
study,
organization,
problem
solving,
and
decision
making.
What
makes
a
mind
map
so
effective?
It
allows
us
to
use
both
sides
of
our
brains
at
once.
The
left
side
of
the
brain
controls
logic,
analytics,
and
details.
It
is
very
structured
and
organized.
The
right
side
is
creative,
imaginative,
and
likes
to
think
freely.
When
someone
says
“think
outside
the
box”,
what
they
really
mean
is
to
move
away
from
the
left
side
of
your
brain
for
a
while
and
allow
your
brain's
right
side
to
daydream,
explore,
and
think
about
the
“bigger
picture.”

a

map

ideas
