Telling your parents what you really want is a risk. Not telling them is a risk too, just slower.

Saying it out loud risks disappointment, an argument, or a lecture, and that risk is easy to see. Staying quiet costs too; it just arrives slowly, as years on a plan nobody updated and a widening gap between what your family thinks you are doing and what you want. One risk is loud and over fairly quickly. The other is silent and compounds.

Find a calm moment with no audience and lead with the thing itself rather than the case for it. One sentence on what you want, one on why, then let them react however they are going to. First conversations are rarely the final answer.
