For context I am thinking about building an Eco house or perusing green entrepreneurship in the next few years.

Right now I am considering one of these two:

https://www.edx.org/course/circular-economy-an-introduction-2

https://www.edx.org/course/incorporating-renewable-energy-in-electricity-grids-2

But I'm looking for something with an application ideally business or engineering related. Has anyone done something similar or heard good things about a specific course?

In my previous role we used toggl to track how long it takes to complete a task and it just seemed like a distraction as it popped up on the screen every 10 minutes.

I'm thinking about using something similar again to get a better idea of how long it takes me to complete a task

What are people's experience with this type of software? Is it worth it or just an annoying distraction?
