Another key aspect to achieve ow is nding
the right challenge. Which sudoku was hard
enough to get you engaged, but not too hard
that it made you want to give up? If
challenges are too low, one gets back to ow
by increasing them. As Csikszentmihalyi says
"If challenges are too great, one can return to
the ow state by learning new skills." In order
to achieve ow, you need to nd the
challenge which bests suits you. If it is too
easy, increase the challenge. If it is too hard,
you need to learn the necessary skills to
overcome the challenge. Do not just give up,
instead practice and keep going ahead with a
goal set in mind.
