Over the years, I’ve written about the importance of being your best because your best self is the one that is extraordinary, effective and high-contributing. This past week I witnessed both ends of the spectrum in different firms.

One partner was scattered, frantic and chaotic. He was unable to maintain any semblance of professional maturity, which made it difficult for others to take him seriously. His directives and deadline promises were met with rolled eyes. Everyone knew he meant well. He just couldn’t deliver.

Another client was focused, relaxed and productive. She demonstrated self control and focus that was compelling. Others listened to her, responded to her requests and were energized to take action. People were inspired and engaged.

Both of these people had significant responsibilities and could have been overwhelmed with all they had on their plates. One mastered the situation; the other was enslaved by it. One was appealing; the other was…well, ugly.

The difference? One focused on being her best by preparing herself for the day. She paused at various times, reminding herself who her best self was and what characteristics and behavior she wanted to demonstrate. As a result, her effectiveness was remarkable.

The other just reacted to whatever the day threw at him. He was busy every moment and exhausted at the end, yet had very little to show for all his efforts.

Which one do you tend to be? Have you taken the time to clarify who your best self is? Having done so, do you remind yourself on a regular basis to be that person? This is the only way to conquer all that is demanding of your time and attention. Otherwise, you render yourself as mediocre. The choice is yours. This week, which will it be for you?
