I decided to take a year off after my graduation, after some online researches about South East Asia, I finally chose Thailand as destination and Openbook for my first teaching abroad experience (it was also my first trip oversea alone). I was full of doubts about my ability for this adventure, especially in the last days before my departure, I was so stressed out that I kept questioning the whole trip and kept thinking to myself "what am I doing? why going so far, why not Mexico, Panama...??". But the doubt was completely gone as soon as I exited Bangkok airport, I was there finally, totally overwhelmed with a mix of excitement, fear of the unknown and joy! I will always remember the feeling of the heat hitting me as I walked out of the air-conditioned airport hall, from 60 F to 100F, that was it Bangkok, Thailand! The day after I met the full Openbook team, they welcomed me and took care of me right away, I knew at that time that I was in good hands and was going to enjoy this experience fully.
If you think about a similar adventure, don't overthink it and just do it! ;)
