To begin, you need to realize that when dealing with humans, you are dealing with irrational emotion-driven biological beings. Humans are hard to predict because they are driven by unseen forces such as the ego. These unseen forces enable people to be nasty towards others of their species, in an effort to win trivial day-to-day battles.
One main realization you need to make when you decide not to let your mental well-being be affected by others, is that others are not right. They are not right in their judgments of you, they are not right in the conclusions they make, and they are not right to attack anything that you do. They are not right to try to ruin your mood. You need to realize that people are mostly wrong, not right. So the opinions of the ones who do not like you are subject to the same error-rate that all human decisions are.
Your realization must include an analysis of how others help you achieve the goals you have set in your lifetime. If your goals are not at all dependent on a specific person, nothing they do or say should be able to ruin your mood. Your emotions are solely reserved for people who matter in your life. Those who have no stake in your success and well-being also have no say in the mood that you occupy.
Cutting the Fat
Analyze the goals in your life and the people who matter. Towards those who do not, be open, welcoming, and kind. They do not matter one bit, and all the actions that you exhibit towards them is a direct representation of your personality. Do not let anyone who does not matter in your life have an effect on your emotions. Realize that you are a human being just as they are. Humans are complicated, and their negativity towards you is just another mistake in their life – which is full of them.
Focus on the next steps that you need to take to achieve your goals. Be fully engulfed in your goals, and make sure that being well-liked by those who do not like you is not one of those goals. Love is, and always has been, non-negotiable. The people who do not like you, will not like you until they decide to like you. Nothing you can do can change those aspects. Thereby your mood should not suffer due to their negativity.
Idolize Who You’re Trying to Become
Conduct yourself in ways that are respectable in your opinion. Conduct yourself like the heroes that you look up to, and do not for one second focus on another human being when it has been determined that they do not matter. We live in a world where everyone desires to be liked. It is a goal which is driven by external positive reinforcement which you have no control over.
If you are focusing on the opinions of others, then you are not focusing on your own mission in life enough. Your mission in life should leave you unable to stand at the end of the day. Work towards your goals with as much ferocity as you try to change the opinions of those who hate you. Look out for your family, and your closest friends. Keep your circle small, and be a good person inside and out.
Chase your goals until you are tired enough not to even consider what other people are thinking of you.
