Mindset is something which constantly carries on in a person's mind. It is an attitude towards someone or something. It can form a permanent impression on the mind and is very difficult to change. At times it can develop into a negative attitude leading to disaster. Your mindset is the sum of your knowledge, including beliefs and thoughts about the world and yourself in it. It is your filter for information you get in and put out. It determines how you receive and react to information. It's often used for a specific part in our life, as in the mindset of an entrepreneur or the growth mindset.
