ser is used for what you are all the time and estar is used for what you or something is right now, in the moment.

Absolutely! The verbs "ser" and "estar" are both verbs meaning "to be" in Spanish, but they have different uses.

1. "Ser" is used for essential or permanent qualities:
- Nationality: Soy de México. (I am from Mexico.)
- Profession: Mi padre es médico. (My father is a doctor.)
- Physical appearance: Ella es alta y delgada. (She is tall and slim.)
- Time and date: Son las nueve de la mañana. (It is 9 AM.)

2. "Estar" is used for temporary states or conditions:
- Location: Estoy en la biblioteca. (I am in the library.)
- Emotions: Estoy feliz hoy. (I am happy today.)
- Health: Estoy enfermo/a. (I am sick.)
- Weather: Hoy está soleado. (Today is sunny.)

To determine when to use "ser" or "estar," consider whether the quality or condition you are describing is inherent to the person, thing, or situation ("ser") or if it is temporary or changeable ("estar").

Remember, this is just a general guideline, and there are exceptions and idiomatic uses of both verbs. Regular practice and exposure to the language will help you master the usage of "ser" and "estar" in specific contexts.
