Stop comparing yourself to others.

Compare yourself to who you were last week or last year.
Not to anyone else.

Love this quote:
“Comparison is the death of joy.” – Mark Twain

And this one too!
“A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms against himself.” Alexandre Dumas 

Develop Power with Grace. 
Asking thoughtful questions is one aspect.
The best questions foster understanding, spark innovation, diffuse negative conflict, and build influence –
