You learn what matters to you when there is nobody nearby to impress.

An audience shapes what you value, usually invisibly. Around people, some of what you care about is genuinely yours and some is chosen for how it lands, and the two are indistinguishable until the audience is absent. What still matters to you alone is a more reliable list.

Ask what you would still do if nobody would ever know you did it. The work, the interest, the way you spend a Saturday. Where the answer differs from your current life, you have found the portion that is being performed. It does not all need changing, but it is worth seeing.
