Don't be afraid of making mistakes.

When I first started learning Spanish, I was so scared I would look stupid when I made mistakes. Now that I am a teacher, I find many of my students feel embarrassed when they say something wrong or are not familiar with a vocabulary word. I reassure them that this is natural for non-native speakers and that even my most advanced students still make mistakes.

History has taught us a lot in every sense of the world from basic trial and error, and this portrays in learning a second language also. We need to learn from our mistakes, keep our head up, and focus on minimizing these errors in the future.

grievance - a real or imagined wrong or other cause for complaint or protest, especially unfair treatment.

Examples: discipline, demotion, classification disputes, denial of benefits, etc.

In a sentence: 

He has a deep sense of grievance against his former employer after he was fired.

The difference between the definite and indefinite articles is the difference between talking about a specific cookie, or any old cookie at all. In English, the definite article is the word “the” regardless of whether the noun it introduces is singular or plural. For indefinite articles, we use "a" if the noun starts with a consonant and "an" if it starts with a vowel.

Indefinite (a or an):

I think an animal is in the garage.

The man is a scoundrel.

We are looking for an apartment.

Definite: 

The boy sitting next to me raised his hand.

Thank you for the advice you gave me.
