Do not confound yourself by considering the whole of life, and by dwelling upon the multitude and greatness of the pains and troubles to which you may probably be exposed. As each presents itself ask yourself: Is there anything intolerable and insufferable in this? You will be ashamed to own it. And then recollect that it is neither the past nor the future that can oppress you, but always the present only. And the ills of the present will be much diminished if you restrict it within its own proper bounds, and take your soul to task if it cannot bear up even against this one thing.
