Morris Villarroel, a Spanish scientist at the Polytechnic University of Madrid, wanted to have a more detailed and complete record of his everyday life, so he could figure out how to live more effectively. Ten years ago he started writing down all the things he did every day, and he’s been doing it ever since.
Villarroel had just turned 40 in February of 2010, when he decided to embark on an epic experiment of self-knowledge and self-improvement. He decided to keep a detailed record of everything going on in his life by meticulously writing all the experiences, the places he was in, the people he met, every 15 to 30 minutes of every day. He thought that this would not only help him better remember everything, but also help him better manage his time and day-to-day life. Nine years and nine months later, the scientist says that he was right.
