Excuse Filipe, he can be a bit of a troll sometimes.
For 6x6, I would recommend watching Kevin Hay's Tuesday tips videos, as they are really good, even for today. https://www.youtube.com/playlist?list=PLjUDKtvFU6ciyTvv_2RextBE_tbHd3Ruu
As for 3x3, make sure F2L is good, and start working on full pll. Jperm has a really good video on 3x3 PLL.
Also fingertricks have to be the most optimal you can make them.
