I find it also much more relaxing if you just go, with less planning, and more surprises. Travel as the wind takes you, that's it.

I usually prefer to make a detailed plan for my trip, but I allow myself to break free from it anytime I find something more interesting to do. This way I'm more sure that I won't waste too much time or money staying in wrong places, choosing wrong means of transport and falling for some tourist traps or common scams.
