5. Journal. Similar to “write it down” above, but with a little more depth. Journaling (whether it’s in a paper journal or online doesn’t matter) helps you explore different areas of your life that you don’t think about much. And this exploration might allow you to find some things on your mind that you didn’t realize were there, some things that can be eliminated or pursued. And just getting these thoughts into some kind of a journal is a way of getting them out of your mind as well.
