3x’s a Charm

Shalom Rabbi, If we do something 3x’s times in a row, does that make it obligatory on us? In halachic terms, would that be considered a neder, a minhag, hazakah, or something else? Thanks

I want more

I am up to date on all the Q&A, Torah talks, podcasts, Jewish myths, and guides. Where can I learn more? Do you give live lectures?
