Last night in Singapore on my comfortable bed

Last night in Singapore. Gonna miss my bed! The familiar smell and all. Was out just now with some friends. One of them asked me if I'm nervous about the trip. I said yes. Another friend later told me to be careful of my own personal security and the likes. Ironically, while I'm nervous of the trip, I'm not overtly worried about my personal security. So what am I nervous about? I guess I'm worried about pushing out of my own comfort zone and finding myself inadequate to deal with it. It's this sense of inadequacy that gnaws at me from time to time which pushes me to go for this trip. So I hope to get a better sense of self after this trip. Wish me luck!
