Hi LeeLee,
No, you are not foolish at all. Sound very sensible to me.
I have never been to Argentina or Brazil but I have been to Cuba and I know you would love it. Havana is an amazing place - such a different culture.
So go ahead and book it. I know it seems like a long way off now but the time will soon roll round.
You question whether you should do a 'big' trip for your first trip but just think what a great adventure it will be. So the answer to that it "Yes". We all started somewhere and you deserve to have a good time. I know you will never look back.
Good Luck and Enjoy!
Be happy,
Best wishes,
