Let's go back to school.

Just for a minute, I promise! Remember back in school when you had to rephrase the question along with the answer? So when you were asked to list the parts of a cell you couldn't just make a list- you had to start with "The parts of a cell are..."
Sometimes if you're using a journaling prompt or writing journaling in response to a question, it can be really easy to just give the answer without the context of the question. For example, if the question was "What was it like to drive a car for the first time?" then you might write "It was exciting and scary all at once!" While it makes perfect sense paired with the question- will you use the question when putting the journaling in your album? Only rarely will you put both into your album. Sometimes the interview format works well, and then you can include it all. That really works well if you're getting points of view from various people or from someone who doesn't normally journal in the album- getting a grandparent's history or a child's point of view, for example.
Most of the time, though, you'll want your subject to be clear just from your words. If you don't want to write a paragraph, check out this post for some fast & easy ideas. Pick your subject, jot down a couple things, and put it all into the album!
If your subject requires more than a list, recipe, or definition: now it's time to break out the school homework skills! Just add a couple words where they're needed to clarify what you're talking about. "My first time driving a car was both scary and exciting all at once!" Then add the rest of your details and memories and you're off & running!
Just a little structure will add a lot to your journaling and help your readers follow you into your memories. Try it next time!
