I have a rather interesting story(gonna be lomg)
There is a german site called speedcube.de and it was late at night so I wanted to go to bed but at least read the Text of it. They have a 50 Minute Video and of their PLL images, so I just did the Alternating Y Perm without explanation and immediatly knew how to do corners and invented Speffz with it. Feeling like a genius, I went to bed. The next day, I couldn't find out how to do Edges(granted, I was just 2-Look), so I looked at the site again just looking at the T Perm and did my first attempt. 12 Minutes - I did Parity by swapping the A and D Targets
Second attempt 17 Minutes - I did parity by doing an extra Y Perm after corners and at the end
Then I saw that this is not getting me anywhere, so I looked at the site a third time. Parity Ra Perm
Third attempt 24 Minutes - it was Friday night and I wanted my Memo to work - I revised so often, I finally forgot it somewhen on Monday, success
This is how I learnt 3BLD
