Here is a good post by Alan Boston talking about feeeling it, and I can relate to that as a muscle memory athlete and sports handicapper.
One thing that will help is if you are making a bet at a sportsbook or typing a bet on line, if you feel anxiety, take a step back and talk of the reasons you are betting. IF you can not speak quickly and clearly about why you r wagering, no matter what the reason, then there is likely force involved. If the reasons flow out of you, if they sound good, then they likely are.
The good news is everyone forces in some aspect of life, in relationships, in a golf swing in sports handicapping, in fact everywhere.
The more you just let things happen, the more you can react to a line rather than look at a line and try to think of who the right side is, the better your results will be, unless of course you have a computer program.
Athletes talk of the "athletic zone" that they occasionally get to. In sports betting, you too can get to that zone, where you just KNOW who the winner is, seemingly no thought. Both frames of mind are the same. Both are very hard to get to. Both are truly amazing. That is flow. GO GET EM
