Building mental strength is about regulating your emotions, managing your thoughts, and behaving in a positive manner, despite your circumstances. Mental strength involves more than just willpower; it requires hard work and commitment. Growing stronger requires you to establish healthy habits, while also giving up the unhealthy habits that could hold you back from becoming better.
Although it's easier to feel mentally strong when life seems simple -- often, true mental strength becomes most apparent in the midst of adversity. Choosing to build mental muscle is the best way to prepare for life's inevitable obstacles.
