Know how to work your head towards unpredictability.
One of the things I learned a lot from playing poker, is knowing how to understand and accept what happens to us in the life of the day.
We wake up every day thinking only of the positive. This is good, and gives us strength to get up on the right foot, but if we are not mature enough, we fall into depression and go back to bed in the first obstacle that life presents us.
So we have to know how to wake up and start the day with optimism, yes, but also know how to have the firmness that the unforeseen will come and that we have to be firm there to face and get around the situations, without despair, without going "on tilt".
So I'm learning more and more to face the challenges with maturity not only when I play, but also in my daily life as a professional.
Hugs and successes to all poker professionals and all other professions.
