Yes, many people still use journals as a way to document their thoughts, feelings, and experiences. Even though many think of it as being something of the past, many people still use it as a way to better understand themselves, their thoughts, feelings, emotions, and to work through things in life.
There have also been studies not too long ago that suggest some evidence on how journaling can actually help reduce stress and anxiety. So the topic of journaling is still very much being researched, and the practice is still being done.
While there are of course digital options to journaling, such as typing on your computer, or even using your phone and journaling apps, many people still prefer to use physical notebooks. The physical pen and paper just have a much different feeling to it. It slows your mind and thought process down much more, giving you the time to go through your thoughts and actually understanding them better.
