In reading and writing, you cannot lay down rules until you have learnt to obey them. Much more so in life.
When pain is unbearable it destroys us; when it does not it is bearable.
Stick to what's in front of you - idea, action, utterance.
Blot out vain pomp; check impulse; quench appetite; keep reason under its own control.
When thou art above measure angry, bethink thee how momentary is man's life.
It's normal to feel pain in your hands and feet, if you're using your feet as feet and your hands as hands. And for a human being to feel stress is normal - if he's living a normal life. And if it's normal, how can it be bad?
