Agreed. I was not trying to imply watching Netflix or doing heroin is the correct way to go about this. But I sorta implied the context of learning a new skill. Like the sibling-post to this indicated: it's about the reward mechanism. But all too often I see people struggling to do something and not really get any satisfaction out of it. The key to learning anything, for me at least, is that it has to be self-rewarding or at least be self-motivating. Just today I did some SMD soldering to try and fix my SO's old discarded Macbook Air, will it fail: probably. Is it hard? you bet ya. At least for me right now. But, I thought it was fun to learn and fiddle with it. I could just as well have decided to learn to play the Cello, or some other thing. Which would probably have been equally "hard", but not as enjoyable for me. And that's the thing I guess: find some heuristic or compass for things that make you go "hey, that would be fun to be able to do" and then push through it. The reward will be greater, and ultimately the energy spend will feel less. For me personally, I know I have very little energy in me. I get 2-3 hours of good concentration per day. Tops. Then it's back to solid sleep. I don't know how people can do hard things for 8 hours straight, but I know it's not for me. (tangentially I think most people can't, they just lie or goof off, and sleep deprivation/burn-out/depression is I think the biggest culprit in our modern society). So I've become very aware of the things I'd like to put my energy in. Like fiddling with electronics, machine learning, philosophy, or astrophotography. But I bet most people would find those things tedious and annoying. So it's up to you :-)
