Day 1: Spanish is its own thing
The first thing to know is that Spanish and English are different! In Spanish the letters sound different than they do in English, the order of words in sentences is different, even words that look familiar to you will often mean something very different and word combinations that make sense in English will make no sense in Spanish.
What I am trying to tell you, right up front, is that you may actually learn Spanish betterand maybe even fasterif you will let go of the idea that Spanish is "like English"; it isn't.
Instead, do your best to remember this:
"Different language. Different rules."
You may even wish to repeat that to yourself now and then.
As the song says, "Free your mind, and the rest will follow." Instead of struggling to make Spanish be like English, just let go of that idea, realize that Spanish is its own thing. Then relax, and allow yourself to just focus on learning how things are said in Spanish.
"Before you can read me, you've got to learn how to see me. I say 'Free your mind, and the rest will follow.'"
