My first entry!

Here is my first entry, so I want to talk you a bit about me.
I'm thirty and I'm from Barcelona. I'm an environmental science undergraduate and I have a Masters degree in marine science , so it is not a surprise that my dream is to go to an Australian coral reef if it was possible, work there (wow!!).
For personal reasons I decided to become a young mother, so nowadays I have three children! haha
Although achieving my dream is difficult I have to try it with all my energy, it's now or never!!
I hope you'll help me, with your corrections, to improve my english in order to make my dream come true.
Thank you!!!!
