Output vs. Outcome in CS/Esports:
At the lower level (and maybe sometimes at higher levels) players DM DM aimtrain aimbotz aimtrain aimtrain aimbotz DM for hours and hours a day thinking that it will turn them into monesy, donk, or shroud. They'll run this routine for days and weeks and months, physically draining themselves thinking it'll pay off eventually. Essentially deluding themselves that "one day something will just click and I'll be dropping 25 every game!". The reality is this never works and the only thing they get is burnt out.
The issue that's happening is these players are equating output with outcome. They're telling themselves that the quantity of work will result in a higher or increased outcome which is a flawed approach. A player might be the hardest worker on the planet, but if they're working on all the wrong things, they'll never achieve anything.
It's very common to see players descibing their teammates or ex-teammates as "hardworkers" but very rarely do they give any insight into the work they're doing to qualify it. When high level professionals use that description, it's most likely the case that they're not slaving away in DMs or demos for 70 hours a week, but rather their work process is extremely efficient and intentionally focused. Most of the time what they probably mean that they're a smart worker.
Which would you rather have?
500% output for a 15% outcome
or
80% output for a 90% outcome
Outcome in a highly competitive field isn't a numbers game. You can't do something poor 100,000 times for the 1 time success. Quality of work has to be the focus.
