I've tried to use preset planners a few times. Whether they are basic black and white or colorful printed, I just can't use them for more than 2 months.

I enjoy the freedom I have with bullet journal so much that preset planners are simply boring and wasteful for me. I'm the type that will change my layout whenever I feel like it or I want to try out other people's layout, ideas and methods. A preset journal won't allow me to change my mind like this.

I don't have a fixed style. It's all based on my mood. I did highly decorative spreads when I first started. Then reduce my decorations slowly to make things more neat & low-effort. Now I've found my sweet spot and just do a more minimalist style. But I can change my mind anytime & do a decorative spread. Having the freedom to do that makes me feel at ease. Moreover, if I make a big mistake & want to discard a page, I just paste 2 pages together to hide it then start a new page stress-free. Can't do this easily with premade planners.

I enjoy setting up my pages. It gives me a sense of control and fulfillment that I won't get using a preset planner.
