Some limiting beliefs can certainly be overcome in this way. However it is also important to acknowledge that some limiting beliefs are based on limiting realities.
An illustrative exchange might be (one that I have had several times):
Wife: I cannot talk to my husband about using condoms.
Response: What would happen if you did?
Wife: He would accuse me of infidelity, beat me, or kick me and my children out of the house.

It is important to recognize the real constraints faced by people, especially women, in order to avoid victim blaming.
