Similarly, as a goal-oriented person I used a variation of the "Waffle House" method, until I turned 40 not long ago. I still have tons of pages in my personal Wiki with life goals, 5-year goals, goals by year, objectives, GTD lists, etc. It served me well, and I am convinced that it is a valid method, up to a point. In big part thanks to this method I also ticked some "societal and cultural expectation boxes". I would cautiously recommend it to younger people too, provided that it matches their personality.
Then, this goal-orientedness fell apart from about age 38 to 40. Having achieved a number of the goals (reasonable ones, nothing to an excess), suddenly all other "goals" turned into a set of stressors. Some - because I doubt I can ever achieve those, others - because I question whether those are what I really want. I accepted the former, but the latter is harder to figure out. This resulted in a 2-year-long haze. The instinctive approach appeals a lot - I would like to think that I have built enough core values to navigate through life intuitively and respecting who I really am. But it also scares, because it sounds like giving up some some control.
Would love to hear the thoughts of those who went through this already. And with all my love, I sincerely wish everyone who reads this to figure out the life!
