Remember, the word thought is not synonymous with the word truth. Your thoughts are not necessarily true or important and you don't have to take them so seriously. Think of them like passing clouds in the sky -- they come and they go. Your true self is the ever-present observer who watches your fear-based thoughts as they pass by.
It is important to know where the flaws in the system are before you are faced with a headline-grabbing instance of police brutality in your city. If your police system has these sizeable gaps in civilian protection (and chances are they do) then there are issues of police misconduct and brutality happening in your city right now, whether you hear about them or not.
When you are living your life focusing on your strengths, you are living in being. What you are good at -- your strengths -- comes naturally to you. The activities you struggle to grasp or never really achieve mastery of are examples of doing that just don't work. Stop telling yourself that you need to be good at everything and focus instead on what lights you up.
