Emotional independence solely depends on your happiness.
These days, people define their happiness based on what others around them say. They wait for other people’s validation before they can boast about being happy.
These validations are usually from other people, who do not even know so much about you nor care about you. Their thoughts about you should not get you bothered in any way.
Some people wait on social media likes before they can accept that they are beautiful. They forget the fact that true beauty lies in your own definition.
You do not need to attach yourself to another person's definition of happiness. Look deep into yourself and choose what works for you, with that, you can be emotionally independent.
