Past that, I guess you have a choice to make: learn something related to things you NEED to know (like studying for the GRE to apply for an MBA or take a drone tutorial because you're a filmmaker) OR learn something simply because you WANT to (like learning to rock climb in order to enjoy your body or learning an instrument simply because you can).
While I definitely invest a lot of time into learning things I NEED to, there really is a lot of freedom and excitement that comes from learning something purely for the sake of learning. So, I always make sure to leave at least 15 minutes a day for that, much more, if I'm lucky 🙂
Hope this helps! Best of luck with the habit building!
