11:11 is a way of the Universe giving quick feedback that has been enabled since digital clocks came about. The number one in numerology is generally about fresh starts- so if you keep glimpsing 11:11 the time is ripe for something new.
I would interpret 11.10 as a helpful sign that the idea or thought just needs a little tweaking & 11.12 as a sign that things are moving along and starting to manifest.
Of course purposefully looking at the clock in the hope it will say 11:11 is not a sign...this is about repeatedly glimpsing 11:11 without actively looking out for it
