I feel like when I get time I should learn deep learning and agent-embodied AGI stuff, business and management stuff.

I just can't see how taking online courses, especially for money, is a cost- and time- effective way to do that.

I think I need to actually build an agent-based deep learning system and run multiple businesses to actually learn those skills. How-tos and background, reading, exercises etc. for all of those things is available online for free for filling in gaps between trying things out.
