Immature mind perceive something as ‘ challenge’ as a target I.e he sees it as something to fight with. He sees it that facing a ‘ challenge’ is uncomfortable and uncomfortability is due going beyond ones limitation and ‘ going beyond limitation’ means breaking of some ‘ old habits’ that what is experienced as ‘ uncomfortability’. If we take a deeper insight into it immature mind will realize that ‘ breaking’ habits’ means ‘ dissolving limiting thoughts’ and ‘ dissolving limiting thoughts ‘ is a process to go through. So ‘challenge’ is not something as final stage to achieve but a series of steps to through. There is never a ‘ challenge’ to face but a ‘ process’ to go through.
