"A" is stands for "Authenticity" for me. Just as letter "A" is the first letter in the alphabets, the first & best thing any leader can do for themselves is to be "Authentic" - real, genuine, credible, true. Yes, true to & for yourself. If you're not true to & for yourself you cannot be truly true to or for anyone else.
We live in a world were there are so many definitions of who or what we should be and if we don't know and are not grounded in who and Whose we are we can easily lose our identity.
We must remain authentic irrespective of the changes and challenges we face otherwise in time, you won't recognize yourself - and many others may not too.
