Dig deeper, Sam. Achievement-oriented people are given to depression both when they fail and when they succeed. If your identity is tied up in your work, then you feel bad about yourself when work isn't going well. That's obvious, and that's the message of this blog post. The implicit message is that you're depressed because you're not succeeding, so get your shit together and succeed and be happy like everyone else.…
The reality is that achievement and success are really quite different:
Achievement is (some examples) - running a marathon, - finishing a PhD, - winning a prize at a competition, - getting promoted.
Success is a higher level goal. For a large percentage of males (individual preferences may vary) this includes: - being well off financially, - the love of a girl/woman, - being popular / respect from your peers, - being powerful and influential.
Unhappiness and depression emerge when your achievements are not in alignment with your picture of success or when there exists the notion of a causality in your head between the two. Finishing a PhD can leave you feel empty and exhausted if your definition of success involves making money quickly. Running a marathon might get you nothing but sore legs if your final goal is to win the heart of a woman.
When achievement and success go hand in hand though I see little very room for depression.
