Looking back on 2019, I didn't get anything of note done and it's making me think a bit.

I have some friends who have made extremely difficult achievements in a variety of areas.
Then others (such as myself) are still shitting around doing absolutely nothing, not fulfilling their potential if they even have any, etc.

The ones accomplishing shit are not necessarily smarter or better than the ones wasting their life away. They just work harder with almost single-minded focus at the thing they're interested in.
What I wonder is why? Could it be genetic? Are underachievers just bound to be who they are? Are there genes associated with conscientiousness?
