This is one of the best lessons taught to me when learning to type in school - if you make a mistake, walk away, refresh the mind and come back again - halfway through 1st typing exam and not one page completed, teacher marching up and down checking on us, said "your running out of time so might as well give up". I was so stubborn and determined that I went through all exercises in half the time allowed and achieved a 1st Class Pass!!! Lesson learned: Determination always wins (we hope!!)
If at first you don't succeed, try and try again :D I love all the lessons in the first post here and those following :thumbup:
