Ask HN:How do track your daily learning progress?

Hi, I'm taking a break from work for a few months. I would like to utilize the time effectively to learn about an unfamiliar branch of computing and try applying it to interesting problems. So it is part learning and part applying.

But I'm afraid I might lose track or balance and not achieve as much as I would like to. I believe tracking my activities daily would help. I should also be able to share it with my accountability buddy.

It would be nice to also be able to map my daily activities to the overall plan to visualize how much progress has been made.

Have you faced a similar situation? How did you handle it? Was there any particular tool that was useful for you? It would be great if you can share your experiences.
