There are some businesses out there who care about every cents they can save from negociations.

For normal people, saving 1c, 2c, or even 5c or 10c is not a big deal.
But for some big companies who need to buy in bulk, every cent may turn into millions if you multiply the quantity desired.

For example, a business requires 100 tons of meat, and each kg of meat cost like $2 (I'm inventing figures here, I don't know real prices).
If the business succeed to negociate the price to $1.95 per kg, that's 5 cents saved.

Now let's do the math:
5 cent x 100 000 kg = $5 000

That's a huge number.

It can almost pay the salary of one worker in the company or even 2 workers.

Same logic applies in language learning.

If you do one mistake in your methodology, like a bad way of learning.

You multiply this by the number of word of a language.

Then the outcomes yields to a huge waste of ressource.

Remember, you can lose and earn money at any time.

But once you waste time, it's over.

You won't get it back again.

You want to learn languages.

You don't want to waste time.

Ressource management is very important.
