If you control your money you control your life.

Expenses are divided into 3 categories:

 Fixed Expenses: They have periodicity and a known amount. They are necessary, we know when we will have to do them and how much we will spend. e.g. rent, services, insurance, etc.
 Variable Expenses: These are those that we must make but both their frequency and the amount may vary. Eg. food, veterinary consultations, etc.
 Non-essential or superfluous expenses: These are those that we make but are not essential. E.g. fashion, hobbies, technology, travel, dining out, etc.

And we must not forget occasional expenses such as Christmas gifts, birthday gifts, etc.

Reducing superfluous expenses, although they give pleasure in the short term, and learning to avoid them or simply control them can generate assets in the medium and/or long term (we will talk about the famous "ant expenses" next time).
