Speaking of your authentic self:
Feel that within you, then allow it to express through you by doing things that feel good. Making decisions that resonate with you. By having experiences and conversations and making choices and decisions, that even if it feels a little awkward at first because you are stretching yourself into something new, you still feel in the core depth within you, yes, I need to stretch in that direction. This is how you know. This is how you live your life as your Authentic Self. You are a part of humanity. You are a part of everyone and everything around you. Doing so from that center of self-love and acknowledgment and awareness of who you are. Take a deep breath in and breathe out.
