4. Practice more frequently, in shorter blocks of time
It’s not about how much you practice, it’s about how frequently you practice.
Training your brain to make long-term memories doesn’t require an enormous amount of time.
What it does require is that you regularly go to the ‘filing cabinet’ (the place where your brain stored that information for the short-term), pull out that ‘file’ and revise it.
Instead of practicing for 2 hours once a week, or 30 minutes once a day, try doing 5 minutes of practice four or six times a day (or whatever works for your schedule).
This way, your brain didn’t have to wait 24 hours (or 7 days!) before you revised the short-term memories and strengthened them.
