I just want to mention that, in the case that your burnout relates to programming too much, you might want to use this time to find something that doesn't involve diving hours a day into an ambitious work. Learning comes at a cost (time + sweat), and might not necessarily help clear your mind, particularly of whatever's happening at work that's clogging it up! It's not what you asked about, but, for myself, if I wanted to clear my mind / avoid burnout, it might be worth rekindling old friendships, or finding out what's going on in local communities, or spending time in nature, or volunteering. That said.. probably one of the most interesting things I'd suggest learning about are functional optics :)
