Through my many experiences with traveling to all sorts of different countries, I have always aimed to be a tourist.
It sounds strange to say so, since people tend to imagine tourists as obnoxious visitors crowded on large buses and hogging the bathrooms. But a real tourist is not someone who signs up for a guided group tour nor is he someone who refuses to stray from a set schedule.
To be a true tourist is to be curious and to be unafraid to wander. You have to be a little adventurous. Yes, discovering things on your own may sometimes lead to disappointment and confusion, and yes, there are times when having a set plan is better.
But traveling is the perfect opportunity for discovery and spontaneity. I find that it is an extremely worthwhile experience looking up from the map once in a while and just trying something new.
