Understanding the way that we think (metacognition) can help us identify unhealthy thought patterns. Our thoughts are based on the information that we process, so it is important that we seek out trustworthy sources using critical thinking skills: categorizing, comparing, contrasting, questioning, evaluating, etc.
The beliefs we hold about ourselves impact our motivation. A growth mindset is when we believe that we are capable of learning and growing, so we push harder and try new things. On the other hand, a fixed mindset is when we view our personality, abilities, and talents as permanent, limiting our potential. Using a growth mindset helps us feel more in control of our lives (agency). Hopefully we align our choices with our values and use our voice for good.
Mindfulness helps us slow down and focus on the present moment, including our thought patterns and how we are feeling. Multitasking stretches our brain to think in many directions, and can distract us from the simplified thinking and self-awareness that mindfulness brings.
