When something feels right, when you know it’s going to change your life fundamentally and you’re sure (or pretty sure) it’s for the better, then you do it.
Even if someone else, or everyone else, believes the opposite.
You are the only one who knows the whole truth of you, and self awareness will lead you to happiness if you can ignore the judgement along the way.
Be careful of delusion. Delusion is self confidence and awareness without the gravity of reality.
