You only have so much to give of yourself to the game. Its not unlimited, its finite. Just like you have only a set amount of money to risk, your brain will only be able to absorb and process a certain amount of this rollercoaster called poker before there is a derailment. We can call it tilt but really it is more subtle than that most of the time. I just sum it up as "I just cant think anymore." I feel the warning signs and flashing lights, "warning, warning, neurotransmittors dangerously low, proceed to the nearest pillow and put your noggin on it."
The easiest way to protect your emotional bankroll is just to keep winning steady amounts in the time frame you have allotted to play. Work a 4 hour shift, collect a pay check and go to the beach. That's a funny joke right there. Larry the Cable Guy
Of course it doesnt work that way, especially if you play tournaments but even cash games have wild swings. Nothing is ever on an even keel. You are either relishing your victory, glad you were able fight back to even, stuck with no more money or fish in the lake.
So here are the big Soupie suggestions for maintaining your emotional bankroll.
1. Exercise. Do push ups, sit ups, go the gym, go out running, get some hand grippers for your desk, get some of these Everlast rubber band things i keep breaking, find something you enjoy and do it. Not only will you stay in better shape, your mental focus and stamina will increase. Most of you have no trouble understanding this, but the hard part is the time and effort. Just look at it as added value to your game. If I exercise regulary, my ROI will improve 5% this year and this means X amount of dollars to me. Thats far more enticing to a poker player than telling him he will have abds of steel the ladies will like. Screw the abds, give me 5% ROI bump

2. Play were you are physically comfortable. A good office chair with the desk at the right height, your main monitor should be directly in front of you, your monitor should be large enough to comfortably see all the tables ( i use a 42" Vizio from Walmart, about 700 bucks, works great). Set the background perfect for you. I went out and bought 2 King sized black comfortors to reduce glare and hung them behind my screen. I also completely blocked the light into the room I play in, white poster board lined with aluminum foil on the inside will block all light and not look to bad to people who pass by. I do use a low level torch light in the back of the room but it doesnt glare on the screen.
Be flexible as well, i have various pillows I can put on my office chair to change the feel or I can just pull up a big overstuffed living room chair for a change. I want to be able to get comfortable when ever I feel the need to change it up. Work in a room with good heating/air conditioning . Its so important to be able to be temperature comfortable to be able to think clearly. I have tried to work in rooms i sweated all day long and I know it cost me a lot of value.
3. Protect your eyes. Raybans outside and Gunnar glasses inside (thanks Rizen). I love my Gunnar glasses, i cant even look at a computer for 2 minutes anymore without them, they have made such a huge difference for me. Be very anal about protecting your eyes from the strains associated with staring at bright lights. If possible, buy full spectrum bulbs for all the lights you will be working under and make sure the lights dont reflect on the screen.
4. Laugh. Find something funny and smile and laugh about it. We all think much more clearly when we are somewhat happy and joyful. Be that way and your bankroll will thank you for it. I watched a show called Worst Week on netflicks instant and laughed my butt off this week. It was as funny as Something About Mary.
5. Eat some quality carbs before and while you play. If you are on a low carb diet, good for you, but your brain needs carbs to fuel the brilliance you are sparking in the frontal lobe. No carbs, no brilliance, no new masterful plan of how to be the next Stu Ungar. Trail mix and fruit are excellent choices while you are playing.
Thanks to Rizen for the title. I think will add to this another time, my neurons are petering out.
