If you can solve the cube, I'd encourage you to learn 3BLD. Or, solving a 3x3 blindfolded. Solving the cube was cool... Memorizing the cube and solving it and taking off the blindfold to see a solved cube, is really damn cool. I remember my 1st attempt taking me 1/2 an hour to get a success, times have dropped, but it's been a while since I did it. I should fix that :)
Any resources for learning Blindfolded 3x3? How long did it take you to learn it?
The OP (old Pochmann) is a super simple method. Learning 3bld if you can already solve a cube is actually less work then learning to solve the cube at first
