Anything that is important to you should be prepared for. Go into a situation/game with a plan of what you’ll do and say, how you might respond, etc. But if things aren’t going your way, do not be so rigid in your plans that you can’t make adjustments.
You should be cognizant of if something isn’t working because it takes time and maybe the ball just didn’t bounce your way at first OR maybe you just had the wrong plan going into the game. Be willing to accept either answer, but be honest with yourself as to why things may not be going your way. Be ok with setting your ego aside, admitting that your plan was wrong, and changing accordingly. Don’t double down on a bad decision.
