Some people have an innate ability to create chaos in their lives. If you are one of these people, you need to get it together. If you create your own chaos, you likely find it hard to get anything done, and the people around you are probably frustrated with you more often than not. So, to stop creating chaos and start having a more peaceful, orderly life, start small and build your way up. Like all lifestyle changes, this will not happen overnight, but if you commit to it and try to reduce chaos a little bit every day, you will eventually have the life you always wanted.
Add a small routine to your day. You won't be able to make a routine for your entire day, so start small. Begin with the first hour, taking care to always start your day the same way.
Increase your routine by a little bit every day. The more routine you have, the fewer opportunities for chaos creation you have. So, if your first hour of routine works for a week, add another hour to it, then another hour after another week.
Make small systems to keep track of things. If you try to organize your entire life at once you will get overwhelmed, so start small. Start by doing something little, like making your bed every day. If you have a freshly-made bed it will be less tempting to put things on it. Next, move on to organizing your desk, then your kitchen and so on.
Buy an inbox and use it. Every single piece of correspondence you get should go in your inbox. This will add more structure to your life as you will know where everything that needs to be dealt with is.
Clean things as you use them. This will further keep you from causing chaos. If you clean a pan immediately after you use it, there won't be as much motivation to put more pans on top of it, thus creating a chaotically-messy kitchen. It will also be less overwhelming to clean one pan at a time than an entire kitchen, so you can keep your chaotic tendencies in check through baby steps.
Commit to making small changes every day, and don't get discouraged if you slip up. This process is going to take a long time, and it is more important to be committed to the idea of it than it is to be following through every single day.
