Some people believe that leaders have to be EITHER kind or tough. Not true at all. You can be both. In fact, I urge you to never feel like you have to explain your kindness or justify your high expectations. The duality reflects your humanity. Love that about yourself. Don't think that something is wrong if you have colleagues who don't share your conviction, or encourage your zest for authentic leadership.
Know in your heart that leading with passion, purpose and love is a beautiful thing. Challenge yourself to be an inspiration to those around you, even on days when you don't feel like it. It doesn't matter how passionate you are. There will always be days when you would rather just do what you're supposed to do and go home. But you won't. You were not born to do just the bare minimum. Only your best efforts will do.
Takeaway: As a leader, you are called to put your whole heart in to how you lead and who you lead.
