The Way of the Bullet Journal
This technique is a tool. While I can't say the bullet journal is the best for everyone, I can say that learning to export data from your brain to other systems is essential for being a creative and productive human being. If you walk away from this unenthused by the bullet journal approach, I encourage you to still take seriously the habits it helps promote.
You are a student. You have code to write. Jobs to find. Bills to pay. Life to figure out. Friends and family to love and occasionally say hello to.
All this is to say: you have too much to do for your brain to handle all by itself.
There are many productivity tools that help alleviate overload of the brain. I do not promise this technique will save you, or even remotely help you, but I do promise to provide you with the information you need to get started and decide if it's right for you.
