The thoughts and techniques are captured on the paper even though the finished design is long gone somewhere. I still remember the process of design through the journal. Some of my pages are more polished than others. Some I wonder what I was thinking at all.
I tend to go overboard with study. I love learning, honing skills and practicing. But summer schedules can be hard to keep up with. Life can be overwhelming at any season and time can escape no matter what our intentions are. One way you can take some pressure off yourself is just capturing ideas, thoughts or sketches in a journal. Just let it be what it is without a specific goal or study routine. Whether you work in pencil or ink like Daniel Ames, just have the freedom to explore ideas. Pencil practice translates into skills with the pen so don't worry if your journal never sees ink. If you keep the journal to refer back to, great. If you toss it out at the end of the book, that's great too. It did what it was supposed to do.
