When I was first learning Spanish I had a Kindle Unlimited membership which allowed me to choose from thousands of books. I read all the books I could find on what are the effective and ineffective ways to learn a language. I chose not to use Rosetta Stone because at least 4 of the books mentioned that this was one of the methods that people tended not to find very helpful-- several mentioned that the free program Duolingo was actually more useful.
I do not think that learning Spanish need to be boring. I took the online course Fluencia (for about $9.95 per month), and finished it in 3 months because I loved doing it. It definitely did not feel like ¨all the same, just new words.¨
It got me to the place where I could understand well enough to enjoy watching telenovelas and movies in Spanish with Spanish subtitles. Watching movies and telenovelas gives me the repetition I need to learn lots of vocabulary without ever getting bored or feeling like I am studying.
Completely agree on that, Thai alphabet is amazing! The whole Thai writing, and for that matter reading also, is so different from anythig i've ever seen before. It took me 6 months to almost get it. Speaking comes easier, though very tricky too.
