What is self-evaluation? Some individuals can be overly critical, some can be not so critical and some have no idea what self evaluation is. From an athletes perspective, you are constantly self-evaluating yourself in every situation. The gym, practice, pre-game warm up, in between periods, during the game, after the game, etc. Athletes definitely self-evaluate a lot but, do they do it correctly?
I'd have to say no. Self evaluation gets categorized with putting yourself on the hot seat in a sense. A lot people do it incorrectly because they constantly look at the negatives and pick apart everything that went wrong instead of the things that went well even if it was a few things. Even if you played a bad game, you definitely did something right or well. Typically athletes don't recognize that they only focus on the negative and beat themselves on that.
It is probably easy for you right now to look back on the week and look at the all the bad things, slip ups, etc you had this week vs the good tings, the little things or the small victories, correct? Why is that? Ask yourself why you find it so easy to pick at the bad things vs the minor wins or little things?
We are so quickly to find the negatives/flaws in our life/games rather than focus on what we are good at it or did well. This is the wrong way to use self-evaluation. The better way to use self-evaluation is to disassociate from the situation and ask yourself how you think you did? From there you ask why you think you did well or why you performed poorly? What made the game go well or poorly. Go over the pre-game, the day before even, in between periods, shifts, etc ask yourself what you did well to prepare and why it worked. This is how superstitions are built along with confidence. When you go over the game and analyze the things that went well and why they went well, you feel confident for the next game and next situation. And whatever you did before that game or during the game that made you play well you stick with it until it does not work.
Self evaluation is a two-way street not a one-way negative loop that just puts your faults on rewind and is replayed in your head over and over again. Ask yourself why before you start evaluating in your head. Asking yourself why in every situation is sometimes a little daunting, why did I do this, that, what made me make that pass, shoot that shot, step here, on and on it can be a never ending loop of asking yourself why. Realize that when you are performing at a high level, the pressure is on and you are in the middle of a game. There rarely ever comes a time where you stop and think. Typically it happens so fluently, without thought and you just react off instinct/gut feeling. You don't think you just do. Therefore asking yourself why sometimes is not useful situations like this. First train your natural instincts and learn to be more confident and trust your gut over asking yourself why after a turnover, bad shift, etc. You don't now why you just acted off impulse typically so by asking yourself why you are going to come up with a terrible reason or you'll say I know why? "it's because I suck, I can't do this. This happens all the time. I am just not good enough." That's what happens when you ask yourself why. Rather self-evaluate the situation after the fact don't think you need to have the answer right away. Wait until after the game, take 15-20 minutes to self-evaluate your performance. Let it settle in and then move on. Get out of your head and move on.
Here's my two senses on how to self-evaluate but not ruin yourself or others.. Realize you are not perfect and never will be, mistakes will happen but how you recover from a setback is the ultimate test to one's character. Understand that sh*t happens in life, the puck won't always bounce your way, things are not going to go well 99.9 percent of the time and I am not saying deflect failure or point fingers but self evaluate and be realistic. Sure, you played like sh*t but there's always another shot, another chance so rise up and control your response to the situation. Don't let one or two failures control you and your attitude. Shrug it off, move on and get hungry for the next opportunity.
