And I would be one of those people.
I did it with French and I did it with Spanish.
The present and the passé composé all the way, every day.
But...I also bought the books and read and tried so hard.
Every time I use the subjunctive (correctly) in French or in Spanish, I still get a little thrill that runs up my leg.
It makes me proud.
Now...
If I could just get straight on the por and the para.
Life would be a dream.
Just do what you did to learn the subjunctive. Understanding por and para is pure practice. There are many quizzes on line that you can try and challenge yourself to figure out why your answer is incorrect if you get any wrong.
