About myself.

It's the first time I am using application like italki and "cada vez me gusta más" (it's getting more and more addicting?) So I'm fine because it'll help/it helps to improve my English.

I'll try to describe myself: I consider myself a normal boy, I've got black and short hairs, I've got brown eyes. I'm slim and I've got more or less good constitution.
I think I am a bit shy to get along with unknown people.It's usually too difficult for me to meet people. But when I know the person I feel better, open minded and extroverted with him/her. 

I like almost every kind of music, although nowadays I usually listen to pop, dance and a bit of rock. Bruno Mars is my favorite singer.
I like playing football and other sports in my free/spare time. Though in last some weeks I have done nearly nothing.

Today I studied and I thought that jaja.
I gave exam two hours ago and I've got one more tomorrow. but I am feeling calm.

PS: how do you say "Creo que es así"?

I think it means "Thanks in advance (Gracias de antemano)".

PS: how do you say "Creo que es así"?

Most literal and accurate: "I believe that is that."

Also good: "I believe that's all."

One I would use: "I believe that's it."
