Very motivating debrief. What should one feel when 790 appears on the screen. And all this with only 19 years

Repect!
Twinsplitter's strategy is the one, which I want to incorporate. I think it was also the strategy, which Dana proposed in her debrief. But, as I think my current level is much lower than the one of Dana or twinsplitter, I would like to first complete all Strategic Guides of MGMAT in their sequence, and then after having a CAT, define the exact order according to my weaknesses. Does this sound reasonable or should I now take a CAT and directly incorporate their strategy of reading the different guides? As I am a real GMAT beginner I should first have at least the basics.
