Write down your daily aha-moments and come back to read again and again. A journal is a tool and repetition is the best way to remember better. So here comes another way to use a journal: write down things you want to learn, write down goals and things you want to achieve. This way you can provide your brain with tasks and program yourself to pursue your goals on a daily basis. Start with something simple, like facts or factoids that you want to learn, write them down repeatedly until you remember them, it also works well with jokes you want to remember but somehow, can’t.
