Life doesn't come with a manual, but it does come with an author for its manual.

I like to keep a small size binder (I hate notebooks because I'm very fickle about organization). Like A5 size with some line ruled paper and some grid paper. I keep some in the back for random notes and extra fill. I use dividers, and the very front page I keep a to-do list of things that really need to happen now. The next page are to-dos that i don't want to forget but aren't really critical.

Then I have a section where I keep one page for any major problem in my life. I'll try to do a root cause analysis. "Just keep asking why". Then I'll sort of journal some observations over time until I solve my problem.

These can be as simple as being flustered in the grocery store or as serious as co-parenting problems. You need to know what parts of your life you can control, and harmonize with the parts you cannot.

Then, I have a section of sort of "how-to's". Simple things can make a big difference, like what order works best for me to get myself ready in the morning.... Like start the water kettle before I wash up and get dressed so I can have my coffee while I make breakfast. A lot of these pages will be written (or rewritten!) after I'm ready to throw away my problem solving pages from the other section.

But on a day by day and hour by hour basis, focus on triage. What can you do for yourself and your people that will have the most impact in the shortest amount of time? What can you do that will bring you a little joy, what can you do that will reduce a little irritation? Then do that.
