13. Stay Organized
Some people like clutter because they know where to find things, and that's is not a good excuse. How many times have you bought something in the store, only to realize after you had it already? And how often do you find yourself missing something? This is an indication that you have too many things, and it is not organized correctly. Furthermore, when it's time to find something, it only takes a few seconds to retrieve it, instead of a few minutes.
The organization is also beyond your physical space. If you find that you are replying to emails late or you are unable to find your digital files, this is a red flag, and your computer needs an organization. Create a storage system that helps you get things done efficiently. When you're organized, you'll find that you can skim through your work and return to doing the things you enjoy.
