The past few weeks I've been trying to make better use of my time than simply watching YouTube videos and neglecting to practise my languages. I've already told you how useful I find Duolingo as a tool, but the reason I've been using it daily is because it's one of the habits I've been training myself to pick up, thanks to an ingenious little tool which has been helping me pick up better habits.
It's called HabitRPG, and it works like a traditional 8-bit RPG: you get hit points and experience - you gain the latter by ticking things off your to-do list, and you lose the former by avoiding your daily tasks (for me, that's usually language practice and writing). Okay, so maybe not entirely like an 8-bit RPG. But the principle is the same; if you lose all your HP, I assume you die. I haven't been apathetic enough to try this yet.
