Some things I have come to over time... Be true. Know the value of authenticity. Lead with your heart. Move through the world with the ease of someone who isn't always looking for something more or better, because it's not where you think it is. (not from a self-help book - just from paying attention.)
I try to remember that I have no idea what most people around me are going through and start from a place of knowing I don't know. It creates a softness where there could have been disapproval or annoyance or hard edges.
