What's the difference between could and should? In a contextualized example, what's the difference if I say "We could see each other more often" or "We should see each other more often"? I'd like to see more examples, if possible. Thanks in advance.

Dreams A few weeks ago I was planning what to do with my life. I just turned 20 last month and everything started running so fast! I had planned writing a book, finishing college, teaching only adults and traveling around the world. I'm scared and now I wonder if I can do it throughout this year. Somebody told me once that I am the size of my dreams... But I haven't discovered it yet. Do you believe you're as big as your dreams?

Olvido Soy brasileña y estudié años atrás el idioma, pero he me olvidado un ratito. Aún comprendo, pero me gustaría hablar con los nativos en la lengua para recordarme del vocabulário. Gracias.

What's the difference between 'so' and 'then'? Also, when do I use 'also' and 'too'? Thanks in advance.

When to use 'to' and 'for'? I've asked this question in a different category. Could anyone help me?

Thoughts I was wondering how many people in the world appreciate poetry, because... "I don't know why I'm feeling like this lately. feeling sick, missing something, feeling tired, guessing that I can't follow my own plan, getting often out of my mind, needing a hug desperately, thinking about someone that isn't mine and whom I may never see again, missing people who don't miss me... But this is life, isn't it?"
