A new language is something that you acquire over a long period of time so there's no need to rush it. Subscribe to YouTube channels for learning Spanish and take notes from them. Write stuff down often! Have dedicated active study time, where you take notes, or have classes with a teacher, and at other times you can have more of a passive approach, by for example listening to music in Spanish or watching Spanish TV shows and films..This will allow your ears to gradually get used to the sounds and many different accents across the Spanish speaking world.
