What are you more comfortable with — routine and planning, or laissez-faire spontaneity?
I like to blend the two together. Having a plan is always a good idea however leaving yourself open to spontaneous events is worth so much more. The best of both worlds after all is a more balanced approach. I am very fond of creating a third option to a duality question and synthesizing my own options in situations. When I went to Paris I discovered that while walking around the city, if you are actively looking for something in particular you will not find it. You will only find it if you resolve that you don’t care to find it and you are tired of searching for it, then you’ll end up standing right in front of what you were originally looking for. So, a plan? Yes it can help, but without serendipity you won’t actually find what you are looking for, not really.
