Hey you! Are you typing non stop but still stuck on your WPM? Why not stop for a while and take a walk outside? Scientific studies show that the human brain is super elastic. When you practice typing, your brain works hard on processing all kinds of information, then if you take a rest, it will have the chance to sort out and digest previous experiences, therefore rewire and improve itself. It's kinda like a spring, you stretch it, and relax it. Over stretching only does more harm than good.
