When you’re vocal about your beliefs and the things you want to do in your life, it can be difficult when you change your mind.
If you openly displayed yourself to the world in a particular way, major change (especially if it contradicts with your existing aims) will come with judgement.
It will come from strangers and people around you but it will also come from yourself. You judge yourself because you have difficulty comprehending and accepting that a person can hold a set of beliefs and then months or years later decide to reject them in favour of something else.
That internal judgement matters more than the judgement we receive from others because if you can’t understand yourself and the choices you’re making, what does that say about who you are?
