I've found that when you distinguish an identity-level limiting belief (a meaning you make about who you are, what I call a "gremlin"), it hits you like a ton of bricks, as you look around and see that it has been running you in every area of your life since you were very small. It's astonishing! And it's a great opportunity for releasing what has kept you from being present to choice, freedom, and opportunity.
I wouldn't bother looking for a "reverse belief" until you've been hit by the pervasiveness and power of your gremlin and looked at the impact it has had on your life; otherwise it'll tend to have you just coping and surviving with the old belief, rather than truly clearing an entirely new space for inspiring possibility in your life. Don't worry about changing it or fixing it; just look. Often, just shining light of conscious awareness on what has been unconsciously running you has tremendous power to diminish it's hold on you, or even make it disappear completely.
To get to the gremlin, take what you've already distinguished (like, "Whatever I say I can do, or will do, or have to do, doesn't work out. Something happens to make things not work out") and add, "...and that means that I am ____." Ask your unconscious mind, not your conscious, grown-up, figured it all out mind. Speculate until you get that ton of bricks effect. When you find it, it will be very, very familiar -- it has been your constant companion for a looooong time.
Another way to approach it is to look at what you habitually think when you're stressed out: What words go through your mind? Notice that they tend to occur like a judgement of yourself, and/or an action you order yourself to take. (A huge one for me was: "I'm trapped - get the hell out" - that would show up in pretty much every area where I wasn't being effective or feeling like I was getting the results I consciously wanted.)
