If you're referring to dealing with difficult or challenging situations in your life, it's important to approach them with a rational and level-headed mindset. Instead of trying to "kill" or fight against these challenges, it's often more effective to focus on finding constructive solutions, seeking help from others, or developing strategies to manage your emotions and thoughts. It may also be helpful to seek professional support from a mental health provider if you're struggling to cope with difficult circumstances in your life.
