do useful aims to provide you with a sense of how much time you spend on different websites.
do useful attempts to guide you to be a more successful learner and to use your time more effectively. For instance, instead of watching the news and wasting time on social media, you could learn a new language, master new skills, or take steps that bring you closer to your ambitious.

The story behind do useful

Hi, I'm Eduard, and over the last few years I've enrolled on many online courses to strengthen my research skills, broaden my career prospects, and to simply learn something new that might feed my curiosity and my passions. Some of these courses were free, and others I paid to take part in. However, I haven't completed all of them. In fact, I haven't even finished half. Often, I tried to find excuses, telling myself that “this week I'm too busy with my work”, or some other responsibilities, or “this week I’ve a lot on socially, so I don't have the time to submit an assignment…” For some of you, this may sound familiar.

One summer day, my eyes were accidentally opened to this problem as I was sitting on a sun-drenched patio, phone in hand, and happened to be checking which phone apps were draining my phone battery. At that moment it hit me that during the last week I had spent almost 4 hours looking at Instagram, 5 on messenger apps, and 2 and a half just surfing the web. I was shocked when I realised how much time I had been wasting—which also happened to be the exact amount of time I had calculated that I needed to study. At this point, I decided to make some changes to my daily routine.

This led me to the idea that I needed something that could help me fight procrastination. I needed regular pushes, or gentle advice from some as yet unknown source. As I tried to explore how a tool could be developed to solve this problem, I met a number of wonderful people who helped to direct me towards this current solution, and helped me to build it. Now I am happy to share this website with you— and please enjoy it, and let it help you to do something useful.

How it works

As a student, researcher, and teacher (all at the same time), I wanted to try and find a solution that could help me to achieve my various goals. However, most of the existing options simply didn’t work, or were not efficient, perhaps because they are not grounded in psychological and educational theories.

To make this extension useful for myself and others, I started to explore frontline knowledge in the field of online learning. I went through numerous research papers published in leading scientific journals in order to determine the features that successful learners might have in common. Then I began to explore behaviour change theories that could help me to change my bad habits and acquire the positive behaviours shared by the best learners. Based on this research, the notifications used by the extension are designed to help counter procrastination, with the aim of enabling users to control their time more effectively. This feature uses techniques taken from the fields of healthcare, education, and marketing.

Over the last year I have explored this problem in depth, speaking to a number of world-leading researchers based at UCL, MIT, University of Edinburgh, Durham University, University of Hong Kong, University of Michigan, among others. With the help of a team of professional software developers and with support from world leading researchers I have some up with an idea: the browser extension, which will guide you in becoming a successful learner.

I hope that you will find do useful helpful and that you enjoy spending your time more efficiently.
