Patient acceptance does not necessarily mean that we do not take practical steps to improve our situation. If it is possible to remedy the situation, then of course we should, but to do this we do not need to become unhappy and impatient.
The greatest battle is not physical but psychological. The demons telling us to give up when we push ourselves to the limit can never be silenced for good. They must always be answered by the quiet and steady dignity that simply refuses to give in. We all suffer. Keep going.
