What Habib said is everything that matters.
You take care of yourself; mentally, physically, and spirtually. Search up "pyramid of needs" and it will give you a lot more insight to how your mental state, physical state and spiritual state matter in not only games but in real life (like dealing with depression).
All in all, take care of yourself and the game will play itsself. Focusing on how to play the game better probabaly will not work, but gaining insight into how you think and making good decisions based on environment is much better than a nomad style of playing.
Those are my tips based on what Habib has said.
