Here are some links to websites that help you figure out the best approach for your needs. There are so many ways to journal. And you don’t have to be a writer. You might just want to make lists. You might like bullet lists. You might prefer calendars. Personally, I keep a daily journal using DayViewer.
I also journal in greater detail by event. For that, I tend to use MicroSoft OneNote. I like OneNote because it automatically updates while you’re adding to it throughout your meeting, event or day. I use OneNote on both PC and Mac. I use it on PC for work and on Mac for other stuff.
In case you’re overwhelmed by the thought of a journal or intimidated by the thought of writing, good news! You don’t have to produce anything amazing. My journals are made up of phrases and lists and words and curse words and exclamation points and doodles and quotes and, quite often, the word DUH. Although sometimes I type it this way: D.U.H.
More on journaling later. In the meantime, think about yours!
Or at least put journaling on your list!
