Ask HN: How do you manage self-study?
478 by ruph123 | 162 comments on Hacker News.
I often feel overwhelmed by the amount of things I either wish to know or that I should know already. Be it theoretical knowledge about ML, CS, mechanics, math topics. Or lack of experience e.g in some algorithms I need to understand, control problems, programming lanuages. And I really struggle to organize a propper study schedule. What should I do next? Should I continue learning this one programming language? Continue reading this ML book? Try to set up and solve some control problems? For each topic I would like to learn, I already have the right material (books, problems to solve, etc.), so at least this is not a problem. Often I am so overwhelmed that I just watch stuff on youtube. I wish I had a tool or found a methodology to a) stay focused on the things I want to learn and b) to somehow track my progress. Are there any tools or methodologies that you can recommend? Please don't tell me "just use pen & paper", I tried and I would like something more interactive.
