I especially think these are important:
2. “Never be in a hurry; do everything quietly and in a calm spirit. Do not lose your inner peace for anything whatsoever, even if your whole world seems upset.”
3. “There was never an angry man that thought his anger unjust.”
7. “When you encounter difficulties and contradictions, do not try to break them, but bend them with gentleness and time.”
8. “True progress quietly and persistently moves along without notice.”
