If you missed writing for some reason that's not in your control, that's fine. Take a deep breath and forgive yourself. In my experience, when I had the luxury of skipping a few days if I had to, it was easy for me to get back into the habit once the stressful situation was over. I skip days, but it's usually not something to feel bad about.
The Bullet Journal system is extremely efficient and it just means that it is doing its job to make sure things are done. Very little writing stands the test of time, and that's okay. Take journalism and journalism, for example, which seem very different. One is subjective and personal, while the other is supposedly objective and intended for an audience.
But the two forms share an important quality that they are not designed to last. Wait a minute and try again. Two and a half decades later, he still publishes at least once a day, and he swears that it is key to the success of his business. If you're interested in trying to write a diary every day because you find it tempting, here's everything you need to know.
In addition, you are more creative when you are tired, so ideas can come up through your writing that you would never have at any other time of the day. If the answer is yes to most of the above questions, then keeping a diary every day is something you should keep doing or trying to do. Writing about your goals for the days and what you hope to achieve, or even talk about the ways you achieved these goals, can be explored further, either in the morning or in the evening. Sometimes I write a to-do list at the end of the day (or the next day) and write down the things I did to keep track of them.
When you write in a journal for days and months, you'll get to that point where you feel tired and exhausted from writing, which can lead you to quit smoking. In general, I would say adapt your design and system to how simple or complex you want and let a day or two go by without beating yourself up. Use your diary to give you that extra push to stick to the habits you establish and change your thought processes that, if you can keep a diary every day, you can surely go to the gym or read that book you've always wanted. Try writing at least one thing that makes you feel grateful every day and you'll notice a drastic change in the way you see the world.
One of the best ways is to give an account on a daily basis of the things you did, the places you have seen, who you met and how your day was in general. In fact, Leo Babatua of ZenHabits says he only writes his diary with bullets; only three to six a day. You can write about anything, even if it has to do with washing three loads of laundry or having a quiet self-care day. When I finally set up a new diary, I always include the lost days and fill the list with brief notes about what I did that day, even if all it says is, postponed like a mofo.
