When you were younger – in school and college, perhaps you struggled with remembering long answers, facts from history / geography, dates, numbers, specifics, names of people? Even to this day I struggle with these things.
My Guru says there are only two ways to overcome this. 1) Fall in love with the content. 2) Repeat/revise/recall.
1 and 2 are inter-related, because if you really love something, you will keep doing it again and again.
The question to Him then, is how to love a subject you really don’t like? His answer: To visualize that you like it. Keep saying that you like it. Keep thinking it, and keep feeling it. It will automatically happen. Not by some magic, but because that is the only language the brain (aka mind) needs and understands.
This is not very different from how a boy and girl who keep interacting with each other soon fall in love!
