What is your definition of independency? Recently I’ve come to realise how are lot of people are co-dependent without even realising it. I somewhat touch upon this in my book 30&Ready.
You might think you’re independent because you have a job, etc But being independent is also having independent opinions or when your actions are not influenced by others.
Put it this way, if you’re able to do certain things alone, such as solo travelling, exercising or eating out without the need to be around someone else then to some degree you’re mentally independent.
