The biggest obstacle and annoyance for you is your own undisciplined heart. A good and devout person plans their actions in their heart before carrying them out, so they don't get swayed by their desires or evil intentions, but instead follow their sound judgment. Who has a tougher battle to fight than someone striving for self-mastery? Our goal should be to master ourselves, becoming stronger than our own weaknesses each day, and continually working towards perfection.
