Time and endless repetition. It helps to actually have a spanish speaker around.
59 years later yo hablo un poco Espanol. And Spanish is probably the easiest language to learn. Just try Nederlands in comparison.
"Easiest language" is highly subjective because so much depends on your native language. Portuguese is going to be way easier for a Spanish speaker to learn than an English one because the languages are so similar.
However, your claim that Spanish is much easier than Nederlands (Dutch) is interesting, because if one looks up articles on the easiest languages to learn--from an English perspective, at least--Dutch/Nederlands is usually near the top. Heck,
this article puts it at #2, behind only Frisian and ahead of Spanish (#3 is Norwegian, #4 is Spanish).
This one puts Norwegian and Swedish at the top, followed by Spanish, then Dutch (Frisian isn't on that list, perhaps because as our first article notes, it's spoken by so few people it's not really something people generally try to learn--or perhaps because the second article is by Babbel, a language teaching service, and they have reason to only want to list the languages they teach). So Spanish seems to be at least viewed as being about as difficult as Dutch is to an English speaker.
Having never tried to learn Dutch I can't opine on it, though. But what do you think makes Spanish a lot easier than Dutch? Dutch has a lot more cognates with English than Spanish does. The main difficulty of Dutch, from what I've heard, is the pronunciations.
