Every person that crosses our path, no matter how short their role is, it is for sure for a reason, every dream, every desire, every fear, every event is designed to help us know ourselves better. Mindfulness is the only way, just observe and be aware or be willing to be aware, and every person, every event is there to help and support you on your path.
