I mean, context matters in everything and nothing happens in a vacuum. From both a practical and a philosophical perspective, relativism is generally prioritized over absolutism in almost every instance. When we look at future planning, sure, there's often a benefit in identifying short, medium, and long term goals. But there's not really a universal rule that applies to everything.
Additionally, when we look at major long term decisions like career changes, they're pretty standard in life. Most college students change their major at least once, the average being 2-3 times (Studentrg, 2025). That doesn't mean they were poorly planned or had some failure. It means that their life trajectory changed.
I don't think there's any way to have a consistent system to make decisions. Just knowing yourself and accepting that much of you are will change every few years. Your interests, perspectives, values, they're not going to be identical to where they are now in just a few years. Just be open to reflecting and go with where you generally find your future to lead you.
