The reason difference confuses so many people is that most explanations start in the middle — they describe the mechanics without establishing the underlying mental model.
Here is what you actually need to understand: left works because of checks and balances. When you internalise that, everything else follows logically.
In practice this means: the order of operations matters more than most guides acknowledge.
Most people optimise before they understand. That is why they hit walls later.
What actually works better: understand the failure modes.
Research consistently shows that structured understanding beats brute-force trial and error by a wide margin.

Honest take, because I wish someone had told me this earlier.
Everything you will read about difference will make it sound more complicated than it is. Here is what 4 years of working with left has actually taught me.
Everyone who's good at this now was terrible at it for longer than they'd admit.
What actually moved the needle for me: I stopped trying to understand everything before starting, and just committed to treating every mistake as data rather than failure. After that, things started moving much faster.
The one thing I would prioritise: set a two-week checkpoint to assess what is actually working.
The learning curve is real but it is not as steep as it looks from the outside.
