Nostalgic It's been almost a year since I last saw the friends I made in Australia. Although I'm happy to be back in my country, I can't help feeling sad when I remember both the good and bad times I went through while I lived in that country. I have kept in touch with some of my friends, but as Australia and Colombia are in different time zones (roughly there is 15 hours of difference betewen both countries) , I've only had the chance to talk to them on skype few times I certainly don't know whether I'll be able to go back in the future. I think all I can do now, is working, getting experience and saving some money, so that it will be likely for me to visit that beautiful country again. I don't want to sound cheesy, but I feel like left a piece of my heart there,so far I haven't gotten used to living again in Colombia and to be honest sometimes I feel like the odd one out. That's why I want to embark on a new adventure no matter how risky it is , I want something that allows me to travel, learn new languages and get to visit different countries, cultures and people. Will I be able to achive all these?, well I better start working on that straight away
