However, bear in mind that plans are rarely followed to execution perfectly. You may meet someone who wants you to stay, or you may get a really good offer. You might experience financial hardship and need to settle down for a while.
When I go on a hike, I spend a good hour or two studying maps (topographical, orthophoto, etc) before picking a trail. It means that I can decide on a whim to follow another trail halfway through if conditions call for it (mud, rain, wild animals, etc). Planning is about mapping out all possible outcomes, and not so much about following one plan to the letter.
