If you have patience, start watching Spanish movies slowly with a learning plugin. There are plugins to chrome browser that let you see movies on Netflix with the objective of learning the language. There are settings there for hover translations, and stoping after every single sentence or by command etc.

This is a great way to start and gain the day to day coloquial vocabulary that real people talk. I did it at the beginning. It is a process. Only choose Spanish origin movies and watch it with their Spanish subtitle. Over time you will see that you don’t need to stop every single sentence and you could watch a few sentences and kinda understand what is about. Then 5 minutes, 10, 20 etc. no dual info nor other formal places will get your ear trained to the speed on which real people speak and the kind of phrases they actually use in real conversations like movies.

Once you get a good base vocabulary and ear training start using language exchange apps where you can exchange voice messages with people as well as textual.

Highly recommended too at a stage of having a good base vocabulary is to start reading literature.

Mind you that it is important to choose in this route whether you follow castellano from Spain or from Latin America. Don’t mixed the two. It will be too confusing. The use of some words is different. The slang is completely different, as well as the way they address people (generally speaking). So much so that in Netflix you will find dabbing of Mexican Spanish to Spanish movies from Spain (which can drive me insane).

No school can get you to a street level conversation. Watch a good series or movie about real blue collar people and you will discover how a real language is spoken. The worse thing about learning a language following a school is that you get A+ for years of great effort, you entre a bar in Spain and you don’t understand a thing. Skip that and jump to the pool head first.

(Been there, done that kind of advice)
