What we pay attention to, and how often we pay attention to it has a huge impact on learning. 

First, pay attention, then rehearse. 

As Julio Olalla a leading coach says:

Practice makes perfect so be careful what you practice 

Work your memory regularly and talk about what you learn with others – ‘Rehearsal’ helps learning stick by coding and recoding working and long term memory.
