One thing at a time

There are going to be times in your life when "everything" will feel overwhelming or "everything" is going wrong. If you can think ahead and imagine what that might be like, how it might feel, how you might react, you can work to create a plan now. That way, when "everything" hits, you'll already have a starter plan.

For me, the mantra of "one thing at a time" helps. First do one thing, then do the next thing, and so forth. Though it is not easy, you will get through it.
