Hello Pheonix,
In my experience limiting beliefs are the very 'facts' we take for granted. They are often cherished beliefs or values, ones we are prepared to fight for or sustain. My daughter believes she is poor at maths - consequently she is - but she didn't used to be. She or someone else implanted a limiting belief in her mind.
I can't resist a nibble of chocolate.
I hate being late.
If only you did/ didn't do such and such, then I would....
I wish I could....(the limiting belief is the 'fact' by which you justify why you can't get your wish).
Limiting beliefs can also be faulty conclusions: I failed my maths test, therefore I am bad at maths.

I totally agree with Brendann. Your limiting beliefs are at the intersection of what isn't working well for you.
Look for thoughts beginning with I can't; I won't; I should; I must; I shouldn't - these are mechanisms that may delineate your belief system.

Look at where you have discomfort and pain. You can turn that on its head and see it as the universe's way of drawing your attention to a belief that MAY need updating, refining, or just plain dumping.

Again, Napoleon Hill comes to mind. "There are no limitations, just those in our minds." What can't you do / have / be?

If all this doesn't put you in touch with some of your self-enforced limitations, then try switching the word limitation for 'boundary', or another synonym.

Finally, list what makes you fearful. Limiting thoughts hold fears in place.

A book some of us have been benefitting from (see other threads) that relates strongly to this subject is "The Big Leap" by Gay Hendricks. It is all about spotting your Upper Limits, and how to live in your Zone of Genius.

I do so hope you enjoy eeking some of those limiting beliefs out into full consciousness.
Adieu,
French Claire
