Microlearning is learning one little thing at a time.
If you have a good documentation and organization system microlearning grows into something significant.
If you learn one principle a day, you will know 365 principles after a year.
If you learn one technique in your area a day, you will know 365 techniques after a year.
Part of the reason why I blog is it is one way I include micro-learning in my life. I write the posts in Obsidian which allows me to find the posts in the future.
I now have over 365 posts that capture one micro-idea that I have.
Over the next year, I plan to expand that practice to document five concepts or interpretations a day. After a year I should have over 2000. I will update how this process is going in a future post.
