I'm thinking to split my online learning in two parts: marketable skills (1) and just-for-fun skills (2).
For (1), I am thinking to go through as many of Andrew Ng's deep learning courses as I can. With AI developing at such a fast rate, it would be beneficial to know how it works underneath.
For (2), I'm thinking to go through a raytracing course and some basic VFX courses on Blender. Possibly something about storytelling as well.
