In the modern age, we get bombarded with information all the time. On top of that, our jobs have become a lot more stressful, having to deal with many more requests coming from email, chat, project management, colleagues, bosses, etc.
This is one of the reasons people struggle to be productive, since it is hard to concentrate when you have many things on your mind.

This is why Routine's console has a minimalistic feel; there is no button to set a date, enter a description, add tags, etc. It has been conceived for you to capture information quickly and organize it later.
By following this very simple technique, you will learn to ignore all the distractions while saving information that might be important enough to be reconsidered later. The time at which you reconsider that information is up to you.
