If there is one thing I can do to make this world a better place is to become empathetic. Being empathetic means you can identify and understand other's feelings. You put yourself in their shoes to feel what they truly feel. That way you begin to understand the validity of their feelings.
Once you understand , you can think of a better solution to the problem. You will have a positive outlook in life that will spread and generate. It erases feelings of hate and hurt which the world needs right now.
