"learning" is not what most people were misled to believe. Contrary to the popular belief:
1. Learning hard is not hard
2. Learning does not mean eyeglasses. Glasses means you made and probably still making a mistake somewhere. I have no direct proof that shortsightedness is recoverable without surgery, but there are people in internet who are trying to convince it is possible.
3. Learning requires much time, but not at cost of having fun and not at the cost of sleep. AT THE COST OF EVERYTHING ELSE.
