The more you travel the better you get at it. It sounds silly but with experience you learn how to pack the right way. I remember one of my first trips abroad travelling around Europe by rail fresh out of high school. I brought all these books with me and a paint set. I really had too much stuff so I've learnt to be more economical.
I have a character failing. I am quite incapable of identifying with anything whole-heartedly. Whatever I am doing I am always planning to do something else. I would rather travel than arrive.
