Ok...mental management...I had issues with this at trials...and I still have to work on it. The biggest piece of advice I can give you is...go get Lanny's Mental Management CD's. Website:
There are others out there as well...and I am not saying Lanny's is the best, but it is the one that I used to help my game.
LISTEN TO THEM. And apply the concepts. THEY WORK. Sure...his voice never changes tone...and there are times it's put me to sleep in the car a bit (I'z gots da audio bookz cuz I'z can't reed too weell)...BUT...the information is priceless. HONEST.
There are several things I had to work on in the beginning, and at times it was almost exhausting to really work the program...but it work. Visualizing...all that stuff works. Confidence in yourself and your abilities blah blah blah.
Another thing I had and STILL have to do...is watch who I am around. Certain people can really affect me, both positively and negatively. A friend told me this once...and I know Susan Garrett has said it before in her blog (and if SHE said it..it has to be true! RIGHT?)...surround yourself with those that are on the same path as yourself. Sure...you might be really good friends with a person that hurts your mental game. IF you want to get better at it, you will have to work on either #1 not letting them bother you...or #2 spending less time with them at trials or where ever it causes issues. Some are more affected by this than others, I am one of those people.
The wrong people will take my focus off running my dogs, and more on socializing, etc etc. I pay hundreds of dollars a weekend to run my dogs...I need to focus on that.
I really have to kick this into gear if I am not trialing much...like the winter. In the winter my MM skills go a bit on the lazy side. And so I have to limit my "people" time...in the summer and fall...when I have been trialing a good deal. I am almost impervious to that stuff...my mental game is strong and just about nothing can set me off course.
Does that make me a bit less social in the winter at trials...yes. Do I lose sight of my goal (running my dogs) yes...sometimes I get caught up in socializing...if I didn't want to socialize I wouldn't probably go to trials. I like people (most days) and do enjoy seeing those I haven't seen in a bit. But too much of a good thing isn't always good :)
When I am walking courses, I go with the handling strategy that first comes into my head (after walking my dogs path of course)...then if it doesn't click with me...I will look at other options. And after walk throughs are over...I mental focus on my execution of all my handling moves. If I doubt something, I have to ask myself WHY I am doubting it. If it is because I want the Q..then I work on banishing that doubt from my mind. If it is because I haven't trained it...I might change my plan..or...in the case of Snooker...to get more points. Mental execution is what I focus on :) I can't run the course 79 times out on the field, but I can run it that many times (and more even) sitting in my chair.
Do I have to do this all the time, nope...I am much better at it now, but I did at one point.
Imagine going to a trial, confident you can run every course, your dog will react how you want them etc etc...not worried about the outcome. It's GREAT, you really start enjoying trials and don't end up with stomach issues (have you SEEN PORTA POTTIES AT TRIALS!!?!!?!? OH MY GAWD)...
It gets easier...IF you work at it. If you don't have a mental management issue (and I believe everyone does to some extent)...then count yourself lucky! :) I work at it, have had to work HARD at it...and now I just have to refresh myself on those skills when the trial season happens again.
Hope this helps...it will get easier :) Just takes time and work.
