Everybody wants the advanced trick. Most people lose because their basics are sloppy.

Advanced techniques are attractive because they look like the thing separating you from people who are good. Usually it is not. What separates them is that their ordinary moves are clean and repeatable under pressure, which is unglamorous and almost never the subject of the video you watched. Sloppy fundamentals do not fail in practice, they fail in the moment it counts.

Audit your basics in whatever you care about. Pick the single most ordinary skill in it and do it slowly and correctly for ten minutes a day. Add the fancy thing once the plain thing stops falling apart.
