I have all these dreams...

I want to do so many things that I think my head might explode with emotions. You know that feeling that you get after watching a really deep movie about how someone's life was changed and then they had an awesome life after they did something blah blah blah? Well thats kinda how i feel right now... I really want to go to Argentina to live, and I think that I will be able to do that once I get that teacher's degree I told y'all about before. Here's whats worrying me: I felt almost exactly the same way about a trip (vacation, not long term) to Oaxaca, two weeks ago. And even though i still want to do the Oaxaca trip, I kind of am not as excited as I was about it. Like for example, two weeks ago, I would spend most of my free time investigating Oaxaca and tourist spots and all that stuff, and now I am searching for apartments in Buenos Aires. I think I am getting way ahead of myself. I mean, I still want to do the oaxaca trip and the teacher's degree and argentina, but I feel like i am getting into a pattern where I decide I want something, get excited about it, and then never do it.
I also saw 21 last night and it made me want to work super hard and make a lot of money and be a bawler (baller?), so that was kinda cool cause it inspired me to work hard and work out and make moeny and gamble and try to be smart (like, genius smart) and stuff.
I mostly love movies that cause this sort of inspiration, but sometimes I just end up feeling like I am failing to do anything....
any thoughts?
