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.
There's no way to approach anything in an objective way. We're completely subjective our view of the world is completely controlled by who we are as human beings as men or women by our age our history our profession by the state of the world.
