Kam, I do think it is a matter of perspective, whether we perceive euphoria to be the end goal, or fulfillment. I draw a thick, dark line between those two. I don't think the perspective of euphoria as the goal is sustainable, because euphoria by its nature is a temporary condition, one end of a wide spectrum of feeling and thus farthest from the middle, or moderation. Fulfillment, to me, is more permanent because it is built on a strong, well-tempered base.
To use the analogy of a number line, seeking euphoria is like jumping from 0 to +9, then rebounding back to -4, and eventually getting back to -1 or 0. Fulfillment is like working slowly, decimal by decimal, from 0 to +2 or +3 and staying there. You'll still fluctuate, but your baseline is a few points higher than it used to be. Maybe that sounds stupid, but hopefully the point is clear. Over time, we operate most efficiently and appropriately at our baseline, whatever that may be, so that must be what we strive to improve.
Shortcuts are well and good for some, it's true that a few of us can take them at leisure and keep on going without breaking stride, but at some point you will have to account for the route you've taken to get where you are. You have to explain yourself, or demonstrate your wisdom in reaction to what life throws at you. Wisdom comes from experience, and when you take shortcuts, you bypass the experiences that give you the appropriate wisdom. For many, though (myself included), that is itself a wisdom that one can only find by taking said shortcuts.
