I know it's subtle, but what you can control is whether you make the best possible shot on goal.
What you can't control is how the goalie reacts to the shot (whether he makes the save or not).
Let me add 1 thing quickly here:
Ask a lawyer to differentiate this for you.
It's very frequently argued in court, the difference between what you have control over and what you don't.
Let me ask you a question, Draisaitl and McDavid are 1 loss away from being eliminated.
The 2 players have been really good offensively, particularly on the power play.
They have been abysmal defensively, particularly Draisaitl.
As you agreed, doing the right things usually leads to goals.
What you can't do is to stop doing the right things and chase the goals, all the while being the cause of multiple goal scoring chances against per game, if not multiple goals against.
I know my parents and coaches always told me to keep doing things the right way because eventually it'd pay off.
What I never was taught was to cut corners and cheat.
