I really "got" SQL about 15 years after I started using it. The explanation is very simple: until that moment, SQL was a minor component for me in a big pie. Then one day I got into the position to troubleshoot some apps with >1 TB database behind them and I figured that SQL is more than simple CRUD operations. For most full stack developers that I know, SQL is still that minor component in the back of their mind and they are usually right.
