Distinguish between solvable and unsolvable worries

Productive, solvable worries are those you can take action on right away (for example, if you’re worried about your grades, you could speak to your teacher to see how you can improve). Unproductive, unsolvable worries are those for which there is no corresponding action (“What if I get cancer someday?” or “What if my children get into an accident?”).
