Yesterday I tried to write something that listed some tips to improve the capacity of apprehension during the moments of study and I ended up learning one more lesson, which was hard and cost me the hindrance of not being able to do it that day. I didn't get a good night's sleep, so I couldn't concentrate on what I was trying to do. At that moment, what I needed was just to sleep. Today, since I am rested, and had a good night's sleep, I can say that the first tip that follows is: get enough sleep!
