Sometimes I draw stuff in my sketchbooks. No rhyme, no reason. Just mindless explorations and experimentations. It's entertaining to see what ends up on the page. When we sketch with reckless abandon, there's no pressure. We can just have fun and see where the doodling takes us.
I like to explore stylistic changes, color effects and different expressions. The benefit of these creative meanderings is that I discover new approaches and ideas.
Also, there's something more authentic and less forced about sketchbook doodles. Amid the mistakes and blunders are a few gems and new discoveries. Plus, it's fun to just sketch with abandon, like when I was a kid.
The drawings often make no sense whatsoever. I've drawn pages of comics with characters making non-sensical comments.
Friends and family who view these pages think I've lost it, but that's okay. The point is not to make sense but to channel a bit of improvisational, free flowing artwork.
Do yourself a favor. Whatever your creative discipline, make more time to explore and mess around.
Try new things, absent the pressure of a finished product. Whether you're a writer, artist, musician, athlete, etc, there's always room for experimentation.
You just might discover new things and take your passion to the next level!
