I catch myself believing in magic sometimes.
There are many ways to get things done. On one end of the spectrum there are unsexy fundamentals. Do enough unsexy fundamentals and you will get results. Everybody knows this.
On the other end of the spectrum, there is magic. Magic supposedly works, according to the witches and wizards who have supposedly used it, but it is unreliable and rarely re-created.
The 80/20 solution is found somewhere between unsexy fundamentals and magic, but it's easy to wander off and get lost while looking for it.
Guarantee results by practicing unsexy fundamentals.
Look for 80/20 solutions where they exist, but don't wander too far.
Stay away from magic.
