Each day, you make a bunch of different choices. Most of them will have some sort of impact on you, both your present and future self. By making a certain choice, “each” self will be affected, so it makes sense that both “iterations” of you will be considered in the decision. However, we both know this isn’t what happens. Most of the time, you’ll make a decision that I can even predict: it’ll be the one that serves your present needs more readily, with little regard to your “future” self. Often, your future self may not even register within your mind.
If you’re not, you won’t have longevity in any craft. Instead, you’ll jump from one activity to another, always ready to call it quits when training gets difficult and you find that you’re wrong.
