I think you're calling happiness success. Success in the form of an impactful career is important, not because it makes the person happy, but because it does more good for others than mere personal happiness. We've had thousands of years of people making friends with each other but almost never curing any diseases or improving quality of life in any lasting way until recently. The friends thing produces value that doesn't scale, so it's not as highly valued as, say, discovering new science which may help all future generations forever.
