Planning is such an important step in acquiring whatever it is that you desire. ‘Winging it’ might get you by a couple of times, but if you are comfortable with gambling your life and prospects away, that is your choice. Having said that, one needs to have an understanding with oneself to not be fully tied to the plan at hand. In other words, while sticking to the plan is great, it is important to also be nimble about it, especially if new developments and information surface. Someone who succeeds will take into account new datas along the journey and make thoughtful assessment to either stick with the original plan or make some needed adjustments.
