Five minutes of honest self-assessment — mood, sleep, stress, social connection, physical sensation — surfaces issues most adults defer indefinitely. Doing it today, monthly going forward, prevents larger issues developing unnoticed.
Five questions
How has my mood been the past two weeks? How am I sleeping? What's my stress level on 1-10? When did I last talk to someone close? What physical sensations am I noticing?
Honest answers (not 'fine'). If two or more concerning, action this week. Most mental health issues respond better to early intervention than delayed.
