6. Get used to looking ahead constantly, look for efficiency over TPS and don't worry too much about hardware, focus on the other things. Hardware is easy to fix, the others aren't.
7. 4x4. Even though 3x3 is my best and most practiced event, I am really enjoying 4x4 due to the increased challenge. 4x4 is my favourite event because its more difficult than a 3x3 but not as laborious as a big cube. Worst however are the small, simple events like skewb, pyra, 2x2, which take algs + tps + little lookahead (exception of 2x2) to master. In my opinion, a good time on a large cube is much more meaningful and skillful than a good 2x2 single, for example.
