Essentially, it means despite the circumstances one can always hope.

That phrase is similar to "The sky's the limit" insofar as the limit of hope is concerned. It is also similar to a phrase they use in your neighbour country, Russia: "Пока живу - надеюсь".

in my opinion,all nature tools will be flexible in your hands depending on what u want .if your hopes are big u can use all possible tools to do what u want.
