What is proactivity?

Proactivity is the behavior of anticipation and accountability for own actions and choices facing the situations imposed by the environment ", ie, being proactive means taking in his hands the responsibility for their fate, whether in life or in a poker session.
Obviously, both in life and in tournaments there are factors we can not control.
With great frequency, great players go to showdown before the last letter with the best equity, but not always finish winning the hand, it is not always that equity is 100%.What they do to be eliminated or losing a lot of chips in a bid gambling by a technically inferior player (who probably did not play well the hand) is not be whining, wondering how it could all have been different if the outcome is another, cursing mentally the player who eliminated them. The best have a resilience (ability to overcome obstacles and resist pressure) very big and know that it is no use whining. They get so angry at the moment, but its proactivity with respect to that feeling makes it last a few seconds, and then are already focused on the more important it is to play your best game, actively choosing how they react to unexpected results.
The opposite of proactive is reactive. Usually this is the main feature of the worst players. The fact that a table has a direct influence on your performance and phenomena as the bad beats impress both earning absurd power to affect your mood and consequently make play worse because the memory of negative results is like a ghost weighing and playing tricks on their cognitive capacity.
I would like to know the opinion of you friends!
Good luck to all ...

I define proactivity as the ability to take over the control of your actions establishing goals. An intelligent proactive person will establish short, medium and long term goals in anything involving his life in order to know what the priorities and so be able to guide his behaviour smartly.

In poker you know that if you are playing on a table you have to set a budget, or if you are playing a tourney your goal is ending up winning a prize. That's a long term goal, but just following that goal will get you nowhere. In order to reach that goal you have to control the middle and short term goals and you do that controlling the way you play. You know that you have to start accumulating chips so you set your best strategy to do so, that i would define it as medium term goal. But in each hand you go you will be playing against other players and show your superiority, and controlling is done by setting short term goals/immediate actions. When a hand starts you must be sure if you are going to win that hand or not, you decide at the first moment you see the cards and you demonstrate your conviction to the people of the table.

Proactive is playing 7-2 off in a limped hand from late position.

To be proactive is to act before a situation becomes a source of confrontation or crisis.

This means you are looking into the future and looking for obstacles and taking care of them before they become big issues.
