Have you ever had something you really wanted to accomplish? Did you go for it? Did you give up on it? Does it feel like something attainable? Or beyond your reach? Where these thoughts and judgments could be coming from?
Stop for a second and notice what you are feeling right now. Is it joy, happiness, love or other positive emotions? Or is it sadness, anger, fear or other negative emotions? Now take a minute to monitor your thoughts. Are you in here and now? Are you in the past or the future? Are these thoughts negative or positive?
