around last fall, i actually started making a conscious effort to smile more in public in order to make myself more open to people as well (even without direct eye contact) because i think i might look a little "unapproachable" when i don't smile. and it's great when someone smiles back.
My ears, well, my eyes are ringing! :D
Same. Exact same thing over here. Just that I decided it one fall earlier. When I learned about neuroplasticity and changed A LOT about my life. Everything basically. :) And that was one of those decisions. Being conscious of whatever I do. I purposely walk upright, smile and think positive. Becoming aware has changed my life. I am so much more at ease with myself and everything surrounding me. And you attract what you send out so it becomes some kind of lucky circle and in the end, you smile automatically for you are simply happy and grateful for all the beautiful things that manifest into your reality. <3
