Talent you have naturally.

Skill you develop through hours and hours and hours of deliberate practice.

No matter how talented you are it does not matter if you do not develop skill.  It takes work.

80/20 rule:  The top 20% skill in each domain takes 80% of the value.  The mediocre 80% share the crumbs.

I didn’t figure this out when I was at school, nor university.  I got through on basic talent and a lucky ability to perform at my very best under exam conditions.

It took a big blow in my life to shake me out of reliance on talent and luck.
