Pride

قال علی علیه السلام:لَا تَدُلَّنَّ‏ بِحَالَةٍ بَلَغْتَهَا بِغَيْرِ آلَةٍ وَ لَا تَفْخَرَنَّ بِمَرْتَبَةٍ نِلْتَهَا مِنْ غَيْرِ مَنْقَبَةٍ فَإِنَّ مَا يَبْنِيهِ الِاتِّفَاقُ يَهْدِمُهُ الِاسْتِحْقَاقُ، غررالحکم، حدیث:7186
Never become proud of a state that you attained without [any] device [and hard work], and never be arrogant of a rank that you attained without merit, for indeed that which is built by circumstance is destroyed by entitlement. Imam Ali (A.S) [Ghurar al-Hikam, no . 7186]
